Most is common knowledge in this thread nowadays, albeit linked to The Two Thrones.The game's VIDEO folder consists of the following tree:When comparing the CD and DVD version, I noticed that only ARTWORKS\VIDEOS and CINE differ in filesize.

Checking this out even further shows me that in those folders, files on the DVD seem to be twice the size of the ones on the CD. My guess is that it's better quality (checked the movies, they appear to be identical in both releases), except for some files in the ARTWORKS\VIDEOS folder.
Here lies the real difference: the unloackable 'artworks' throughout the game seem to differ between both releases. Startling discovery is that the file VIDEO06.BIK on the CD version contains a profile of several enemies, worth about 4MB. On the DVD, this file uses a whoppin' 687MB, and doesn't display an enemy profile, but instead shows a documentary about the history of the Prince of Persia series.
So, concluding: not ALL movies on the DVD release have better quality, only some have (and it isn't really noticable I might add). However, the DVD and CD version DIFFER in the sence that the DVD version contains movies not found on the CD version (and I think it's vice-versa too).
Unless there's something else explaining the increase in size on the DVD version (like the soundtrack consisiting of multiple languages), I think this is all there is.
Also, the CD version seems to feature gore like decapitation, whereas the DVD version does not. According to the nforce forum, the DVD crack for the game works on the CD version, yet removes some of the gory features as well.
