My favorite movie is Kingdom of Heaven. Its not available on hd-dvd yet. So here is what I did used dvd shrink to make a backup copy (saved to a folder instead of a dvd disk). Then I used ulead movie factory to create a hd dvd structure. The movie imported as a 24 bit 16X9 with 720x480 at a size of around 4.3 gig. I used the setting of 24 bit 16x9 with 1920x1080 and compression setting at 100 for greatest quality. After burning to a regular dvd I couldn't check it (wouldn't show up in the drive) but it would play in windvd but in my toshiba A2 it showed up as a hd dvd not just dvd and a resoultion of 1080i. The quality seemed alot better than the original at 480p and the upconverted backup dvd. After I get some double layer dvds I will backup with no compression in dvd shrink and use 2pass in movie factory. Someone may have already done this but I guess it is an option with not many choices for hd backups yet. Also you don't want to rip as a avi it uncompresses at around 13 gig in movie factory.
