Spy Kids 2 has so much extras that in total is around 8 gig. The default in IC is to compress the video portion (without audio) to from 3.82GB to 1.58GB in order to make room for extras. I ran it (bumped the menu quality to 100% - probably shouldnt have) and the image was 4.5GB (too large), so then I adjusted some things down so it predicted a 4.22GB image (just to be safe), tried again and in reality ended up with a 4.31GB image. I burned and the resulting quality is not that great. I could try again and take out a bunch of extras out but I don’t feel like wasting hours or days messing with this, considering it takes several hours each time. I ran it through DVD2One - took 15 mins. Since the main movie is only 3.82GB, and the AC3 portion (only audio stream I kept) is 323MB, that equals around 4.1GB. There is actually no transcoding done in this case and the result should be 100% same quality as the original (my image with DVD2one was only 4.1GB, not 4.3GB, so this proves).
I sort of am leaning back to the idea how DVD2One does things now instead of trying to preserve all the menus and extras like IC, which I probably will never use anyways. Way easier to pop a DVD in and watch the movie rather than messing around with clunky dvd menus in order to get the damm video started. Easier for the kids also. All I am doing this for is to backup the kids dvds I buy so they can watch on their own TV and not worry about destroying the originals.
Others though, like Time Machine and The Matrix come out really good with IC.
Instant Copy is also easier for a multi-episode DVD at this time than current version of DVD2One.
