hey, first post, i had a look for such a topic but coulnt find one so thought id sign up and create one. I have begun making backups of my movies using anydvd hd. First up was Black Hawk Down Blue-Ray, once id ripped and merged the two mpeg files together i was left with a 35gb file. BHD is a pretty god movie but doent quite warrant 35gb of my hdd space. Is there a way to shrink it down without too much loss of picture qaulity? The reason i ask this question is that a recently viewed a downloaded copy of transformers 720p at a mates and it was only around 6gb in its .mkv format. The picture quality i have to say was better than my 35gb movie, so obviously whoever put the movie up on the net managed to convert/shrink it to a much smaller file with mimimal qaulity loss. Does anyone know how this is done? Would appreciate any comments/thougts.
