Here are three tips for authoring HD DVD in Ulead VideoStudio 11. (I capture and edit in Vegas Pro 8, render out to m2t using the 1080i template. Vegas smart-renders, so the video that isn't edited or effects added is not re-rendered, thereby keeping the original video quality. I'm authoring 1080i media assets to standard DVDR)
1. VideoStudio will not re-render compliant files when you author, but ONLY if you import the files directly into the "share" submodule in the VideoStudio Editor module. If you put your media on the VideoStudio Editor timeline and author from there, VideoStudio will re-render your media even if they are compliant.
2. If the "insert chapter" buttons are greyed out and the jog bar is not appearing, download and install the latest DirectX update.
3. Your DVDR media quality is much more important with HD than SD (I think because of the higher bitrates). I did a test burn to Ritek budget media (which has always worked fine for me for SD) and got audio dropouts and video stuttering. Burning the same .iso (I author to an .iso image and burn with Nero) file to premium Taio Yuden media resulted in perfect playback.
Hope this helps someone.
