I've been using DVD Shrink for awhile. I'm trying to backup some anime dvds, and several of them when put into dvd shrink will not compress to small enough to fit on a dvd5, not only that, but they will not allow me thew option of downsixing the size of the dvd any further. Now here I have 2 Anime dvd's I'm trying to back up: Gundam Seed TV Series disc 1: Original ISO file size before importing into DVDshrink is 8,215,462 kb After importing into Dvdshrink, It compresses it down to 4464 mb, meaning the whole bar at the top is green. perfect! (average compression ratio of about 55%) Trigun Tv Series Disc 1: Original ISO file size before importing into DVDshrink is 7,571,694 kb After importing into Dvdshrink, It will only compress it down to 5,233 mb, and it won't let me compress it any further! Now this is only a compression ratio of 67%, why will one compress, and one will not? I need some help!, Thanks.
