Cam - very few films these days tho have any (or noticeable) artifacts in them - and the idea of HD-DVD is that the quality of picture will be five times better than before, due to increased storage capacity of the disc, and the fact it will use a 405nm blue laser rather than a 605nm red laser (as current DVD's use) to read it, meaning a tighter "pinpoint" on the disc surface from the laser.... Audio is going to be 3 times better, and the majority of discs will support both DTS and 7.1 sound configs. HD-DVD is also designed specifically with 1080p HDTV resolution aswell...
