I am trying to copy "Steve Vai live at the Astoria: Disc 1". It is the biggest disc I have ever seen. In DvD Shrink, with an automatic compression rate of 58.3%, it is still 5,489mb! I can't adjust the menus or extras any further, and if I re-author, just the main title alone is 7,811 uncompressed, and 5,478 compressed to the max! So my only choice left is to maybe exclude some audio streams. I have never had to do this before, and I am not sure which streams I need for a good quality copy, and which are possibly extraneous. The choices are: LPCM 2-ch English = 1,557mb AC3 5.1-ch English = 452 mb AC3 2-ch English - Director's Comment = 194mb If I leave out the LPCM, it fits great, with an acceptable rate of compression of 67.8% However, If I leave out either one or both of the other two, it doesn't even make a dent in the overall total! What should I do?
