I think CloneDVD2 PQ is better than DVDshrink. I would like to see clone add some of the features of shrink, such as the variable compression rates by title. I'd also love to see a full re-code engine like DVDrebuilder. I don't care if it takes a lot longer, to encode, I'm all about the best PQ.
Kudos to Oli for the consistant updates to Clone, it just keeps getting better.
