Computer recognizes DV but not HDV

[AmethystWeapon]

When I plug my HV30 into my PC's firewire port it recognizes it when it's in DV mode but as soon as I switch over to HDV mode the computer acts as if I removed the camera from the firewire port. Has anyone else had this issue?

[voodeux]

Dude, you've got to include some more information about your system. What you just told us is that you have a car, but it doesn't start on Wednesday (and you'd like to know why).

[RScottyL]

Well, the first couple of common reasons I can think of:

(1) You recorded in DV mode, and your footage is in DV. You are now exporting, and it is being captured as it was recorded.

(2) You recorded in HDV, but unfortunately it was set to export in DV mode, known as "DV Lock". Check your camcorder settings and make sure it is set to export in HDV instead.

(3) The capturing program you are using cannot capture HDV, and will only capture DV instead. Make sure to use a program that can capture HDV. Windows Movie Maker for Win XP will not capture HDV, but DV video instead. You must use a different program to get it to your computer!

(4) Some pirated/hacked/sliptreamed versions of windows don't recognize HDV. You might want to consider checking your Windows authenticity.

My HV20 doesn't show up in the safely remove hardware widget when it's in HDV mode, though it does in DV mode.. but HDVSplit, Premiere, Vegas, etc all see it and are able to capture from it. Your capture environment will let you know if the camera is available or not -- there's really no reason you need Windows to "see" it.

No need to be rude, voodeux. I'm running Windows XP version 5.1 with (I know it's old) service pack 1. Is there anything else about the system I should mention? I've tried using HDV Split to capture my HDV footage but it states that it doesn't recognize it. I'll see if DV lock is the problem.

You might go ahead and update your install of Windows XP.

We are up to Service Pack 3 now!

[tcindie]

Agreed. I know there was some firewire stuff that was included in service pack 2 (or maybe just after 2, so it would be in sp3 for certain)

[Erik Bien]

I second that vague recollection; I believe there was a problem with the XP SP1 drivers that would "lose" the ability to see the camera as an HDV device after it had connected to it as a DV device. I recall the recommended solution was to update to SP2.

Service pack 2 is minimum requirement for HDV and the programs that support it. And most programs will lose connection on camera mode switch. You have to physically disconnect, switch mode, then reconnect the camera to the computer.

Yo, Amethyst. Voodeux WAS NOT being rude.

You are the one who posted a half baked question leaving the rest of us to try and identify your particular problem from a whole myriad of possibilities.

If you would have had the same respect for the forum as you obviously so demand, you would have included as much information as possible in your op and not only after someone called you on it.

I think Voodeux responded apropos to your op.

Be glad I didn't get to it first.

[AmethystWeapon]

Well gents, I updated to SP 2 but still the same bull. I tried the DV lock function and no go, tried CycleWriter's suggestion and nothing. Totally stumped.

[thirdflr]

ever solve your issue? Because I have it to!

I had once the same problem: When my computer was fed with DV-Stream (not HDV), Windows XP SP1 found immediately the appropriate driver and allowed the video to be shown on the screen.

When I switched to HDV, Windows complained about not being able to find a driver for an obscure "AV/C subunit" - the display of the video was not possible.

I had to search through huge dephts of the www to find a solution:
After Windows won´t find a driver for the AV/C subunit, it will allow you to manually install a driver. First select the option to install software manually from a list or source, and then click continue. Next select the tab on the bottom (I guess it´s "Don´t search, but select the driver manually" (I don´t have an English WinXP right now)) Then you will see all available types of hardware you can select from. Leave the option "show all devices" selected and click on continue. It will take a while until the list will be shown. Now you can see the company on the left side and the driver on the right side. On the left side, select "JVC". Now you should see a couple of drivers on the right side. Select "JVC tape drive" and click continue. Windows will probably give out a warning on the compatibility of the driver, but click on yes. The driver should be installed after a few seconds.

Through this method, I could enjoy watching HDV videos on my computer screen. I use VLC player for watching my stuff. But HDV split should work as well.

I guess the driver is designed for D-VHS recorders who output HDTV from their firewire ports and who apparently use the same MPEG2 compression as HDV, but I´m not sure.
Don´t forget that this method even works with Service Pack 1.

when i got my hv30 a few month ago i had the same problem. my powerbook recognized my hv30 just in dv mode when i switched to hdv it lost connection. after hours of messing around without success i made a RESET on my hv30 and suddenly it worked. crazy, but since then i never had a problem again!

I have this exact same problem where I cannot get my Canon HV20 to be recognized in HDV mode. I run XP x64 SP2 and it used to work. I recently reformatted my PC for a clean install, and as far as I know, I installed from the exact same CD with the only difference being latest drivers, latest codecs and latest Windows updates.

Premiere CS3 thinks my camera is offline, HDV Split sais it does not recognize my camera, and only Avid Xpress is able to control the camera's playback through firewire, but only the audio channels are coming through. The camera is in HDV output mode and the loaded tape contains HDV data.

I have tried the hardware reset button but it didn't work. I did get the AV/C Subunit driver installation dialog everytime I connected the camera. One time I tried to install avc something (don't remember exactly) and it said "installation failed". Ever since that moment, the dialog does not show anymore. Also I cannot find AVC Something in Windows' Hardware Manager so I cannot try something else. Now I cannot try Eclipse's solution.

I sooo do NOT want to reinstall Windows. I just did it a month ago and I wasted a few days setting stuff up. Any suggestions?

[Redsandro]

I installed a very recent image and the AVC dialog was back. I read this recommendation:

4. Another pop-up asking for drivers for that device.
5. Select "Install from specific location".
6. Select "Do not search, I will choose the driver" etc.
7. Select "Sound, Video and game controllers". (You may need to uncheck "Show compatible hardware").
8. Select manufacturer as "JVC".
9. Now select model as "JVC Tape Device".
9. Force it to use this driver if prompted.

But XP SP2 x64 has no JVC brand in Sound, Video and game controllers.
Anyone tried one of the hundred others?

[Redsandro]

Wait a minute, I think I might have used that nLite'ed XPcd that I also used on my virtual machine. I removed a lot of stuff for that, including 'Tape Devices'. I thought these included those datatapes from back when only, but I'm starting to think it's likely that this also included that JVC Tape Device thing.

Next question is, how do I install this from the original CD if I used the crippled CD for Windows installation? Removed components are not even listed in the Add/Remove Windows Components from the Add or Remove Programs dialog.

[Redsandro]

YES!

This worked.

After wasting 6452 years of my life, google showed me this post on this very forum:

avcstrm.sys and mstape.sys I've found in C:\WINDOWS\Driver Cache\i386\sp2.cab and mstape.inf I've found in Google Put all 3 files in some folder and use them while installing the "av/c subunit" device

Ofcourse I didn't have these files but I installed Windows from the original disk onto a virtual machine just to get the files back.

The files are spread in three locations:
C:\WINDOWS\Driver Cache\amd64\driver.cab
C:\WINDOWS\Driver Cache\amd64\sp2.cab
C:\WINDOWS\Inf

There is no need to google the files and this way you're sure to get the proper files for x64. It works! Thanks for the help people!

Hi, my first post and I had been experiencing problems with my software recognising HDV so I thought I would let others know what made it work! This is with Win XP SP2. These are instructions written by a layman for a layman, I hope they help!

I tried the following (thought it best to let you know each step just in case an earlier step works for some here):

a) I pressed the reset button (take out the battery and there is a small reset button), this then enabled direct capture in HDVSplit (ONLY in "Camera" mode and ONLY if the camera is on [and in camera mode] when inserting the firewire cable into the camera [the PC end was connected at all times]. I could now record a valid .m2t file from live camera mode recording but capture from play mode was still a no-go.

I could switch from camera mode to play mode quickly and it would seem to work and record prefectly but at the end I would get a null .m2t file which was always 0kb in size.

b) As many have said you need to be sure that the camera is set ot output in HDV, and not DV locked. Because I am a bit of a dunce I found it difficult to locate that, even with the manual so here are some foolproof instructions on how to get there:

In "Play" Mode > FUNC > MENU > PLAY/OUT SETUP2 > DV OUTPUT [set this to HDV/DV]

If the DV Output is greyed out you need to take the firewire cable out from the camera, you will then be able to change it.

As for drivers I did not need to install any drivers, the only software I installed was the CD that came with the camera. I hope this helps someone!

Hello everybody!

My name is Marian and my head has been spinning in the last few days, spending countless hours online to find a solution but with no luck. I bought an HV-10 a few days ago (because of it's compact size) and havn't been able to capture it still even though i have some very nice footage (2 tapes). I have an xp sp3 stripped down version, Dell XPS Gen2 with 2.13 centrino, 770, 2 GB RAM. At first, the pc wouldnt even recognize the camcorder, it recognized it as AV/C subunit under "Other Devices" and Power Director, Vegas Pro didn't even recognize it. So I uninstalled Canon's software and re-installed it and I was able finally to install Canon's drivers manually.
Power Director 7 (supports HD) recognized the cam and the play controls works but no video and once I hit play it will play for 2 sec and no video and then I would get the message "you can't use the capture function because the iLink mode on HDV machine is not identical to the recorded format on the tape etc..." So I tried Vegas Pro and it wouldnt even recognize it (device unfound or something).
I have a Sony DCR HC1000 and I have no problems with capturing. On my HV-10 I have it on AV-DV lock OFF and HDV out. I tried resetting it and nothing. I also tried with DV on but still no video but there's recognition with both power director and vegas Pro.
Can somebody please help me out? This is been giving a headache for a while now and so much time online reading the different forums. Yet I havn't captured one sec worth of video I got in HD.
I would greatly appreciate it whatever input you might have!
Marian

duh, that is discussed in this very topic :P
Sorry if it won't work like that, then I'm sorry.

hi,

hope im not too late and someone reads this!
i am trying to capture footage with my hv20 through Nero 9 - it is supposed to support HDV and blu-ray.

every time i try the capture stops after 1 second.
Nero seems to capture fine when i am in DV mode but does not when i am in HDV mode. i have the settings correct on my camera ie. output as hdv etc
when in DV mode Nero recognises my camera as 'Canon DV device' but when in HDV it is listed as 'Microsoft av/c tape subunit device'.
im connecting to a dell laptop via firewire and am on vista home premium (32bit)
firewire connection must be ok as i can capture in HDV on Windows Movie Maker on same laptop.
i know i can continue to capture on WMM and upload file to Nero but that is a pain when Nero 9 should do it.

any solutions?
thanks

[Redsandro]

Sorry, don't know about Nero, but there's a tool that captures the HDV exactly how it is from your HV20. It's only like 5 bytes big so this program won't give you any BS. You can feed the resulting captures to Nero, which would have to do transcoding anyway so timewise it's not a pain.
