What does a non-progressive DVD-player do with a progressive signal?

[Lou van Wijhe]

I'm planning to buy an HV20. Studying the 25p (PAL) shooting option I wondered what my non-progressive DVD-player would do with a 1080p signal.

I do understand the advantage of storing images in a progressive manner. But am I right in assuming that there is no harm in playing them on a non-progressive device? Or is there even an advantage compared to the conventional interlaced signal?

The 25p footage of the HV20 is playable on any device, whether it's progressive of not, as it's stored, or may I say 'disguised' in a interlaced container. It's still true progressive, though.

Remember, however, that your DVD player, unless it's a HD DVD or Blue Ray player won't be able to play the HD clips of the HV20 from DVD (or memory stick/harddisc if it's USB capable), unless they've been downconverted to standard definition.

A blue-ray burner and player is also in the planning but I'll downconvert to SD to start with. Thanks for responding!

Related to what the OP asked:
So why the heck aren't all DVD releases from the past few years in progressive scan?

Oh, that's right.. purposely gimp the existing format so we have another incentive to upgrade to the HD discs. Slick.

Once you have seen how poor motion portrayal is with 1080p 24/25, I am surprised you would want to use it over 1080i.

DVD is an interlaced format, although the video contained within the interlaced stream can be interlaced or progressive, just like the way the HV20 stores its video on tape.

Once you have seen how unartistic motion portrayal is with 1080i 50/60, I am surprised you would want to use it over 1080p.
