I have been having problems trying to back up the Movie "Terminator 2" with DVD Shrink. I've been using it a lot and this is only case that has presented problems. The Disc is 7.61 Gb and DVD Shrink only manages to compress it down to about 4.6Gb, ie. too big to fit onto a single DVD-R. Could it be that there is a maximum compression ratio? Although I find this unlikely since the program allows several movies to be accomodated onto one disc. Any suggestions?
