I might be able to do some screencaps of a dvd and hddvd later in the week (I have serenity on both so that should make for a good comparison), what resolution would you want the display set to for the dvd (as I would assume you dont want to see ffdshows scaling just the hqv scalar), I can definitely set windows to 720p and 1080p for the hd-dvd, not sure what will happen if I try to run vista at 720x480 for the dvd.
