I never have been able to figurre out why DVDShrink appears to go backwards on manually selecting your compression. Almost all movies my kids have I backup I do the whole thing because they like all the special features. Mostly DVDShring selects in the area of 71.4% on automatic for example. If you manually choose your compression and move the slider down to say for example 45% from the 71.4% the file size actually gets smaller on the slider bar, not bigger. I never understood this, less compression should mean a larger file but better quality. What I always would like to do is have the least compression on the movie and the maximum amount on the special features possible. What am I seeing wrong in the interpretation here?? Even if you select just the movie file, it works this way, slide the compression bar down and the file size gets smaller.
