I know that there are plenty of DVD compression softwares out there. I've used CloneDVD2 and Amazon's DVD Shrinker. I noticed DVD Shrinker did a better job of compression, by creating less distortion and coming closer to the custom target disc size. I am actually merging two full length movies into one file, then compressing them to fit on 8.5MB disc. My question is, are their any softwares out that are notoriously popular for superior quality? Or are they all the same?
