I was trying to figure out how to get Gangs of New York on 1 disc and I couldn't find a way to do it in the forums using DVDShrink, so when I figured it out I decided to post it up here for anyone who wants to put combine 2 discs onto 1. This can be used with a movie that spans 2 discs, or with 2 movies, if you don't care about a little reduction in quality. This instruction assumes you know how to rip movies with DVDShrink. First, take the first disk and rip just the movie off of it, with as little overhead as possible. With disc 1 of GONY I was able to rip just the movie with one audio stream and not need to compress it at all. Once it is ripped, open DVDShrink again, click on "Open Files", and find VIDEO_TS.IFO from the disc you just ripped on your HD. Then put the second disc in the drive. Hit "Re-Author" on DVDShrink, then Open the second disc. Hit "Re-Author" again, opening up a third copy of DVDShrink. Then you just have to drag the two movies into this blank window and hit "Back-up" to create the final disc with both movies on it. Don't forget to trim down the movie from disc 2 by eliminating any unwanted audio streams. I was able to get GONY on one disc, with both halves at about 50%. I'm sure some people will complain that this is too low quality for them, but I have a hard time seeing the reduction... probably because I don't have a high-def set yet. Please let me know if this was helpful to anyone, and if anyone has any questions or problems I'll be happy to answer them if I know how.
