>> Aren't the DVD's for Princess and Arabian Knight single-layer anyways? If so, your edit doesn't really matter if it's dual or not.
I'm not using the video directly from Arabian Knight - it was converted to PhotoJPEG 24p and remastered slightly, so whatever bitrate it had on that DVD doesn't matter as it's being recompressed. My cut is also a lot longer than Arabian Knight. I also added a few special features, so it came out at 6 gigs.
Anyway. Yeah, the single layer version still looks fine. This was also true of my Return of the Jedi edit, where it was designed to work on a single layer disc, and looked great, but despite my saying over and over that the single layer version was equal in quality, people wanted a dual layer version anway. So that's what I've done here too.
The versions I'm actually giving to the animators are single layer, so yes, I consider the single layer version the true version, it's fine that way.
