Dumb question time. Since 480x480 isn't an MPEG2 standard, would it not be better to change an entire program to 352x480 when pulling it into SpruceUp for the best chance of compatibility with set-top DVD players?

If you change it to 352X480 you'll lose resolution, which kinda defeats the purpose of using a DTivo for video extraction. It would end up with the same resolution as a SA Tivo. The only reason you need to patch the 1st header is to fool the authoring program into believing the video stream is a DVD-compliant format. Once the preview files have been generated, the 1st header no longer needs to be patched. I can't be sure, since I've never tried it, but if you transcode the entire file to a different resolution it may actually look worse. Virtually all late model set top players that I've tried have been able to play TyDVDs having 480X480 resolution with no complaints.
