I have an NAS and just got an HD Media Player to stream all the stuff I have stored on my NAS to my TV. I've started copying my DVDs (DVDs that I legally purchased & own - no crap please) to store them on my NAS to access them more easily. The total file size is between 4-7GB. I've seen some of the movies downloaded off the internet that claim to be & sure look to be DVD rips, yet they are under 1GB - what I want to know is what program are these guys using to compress their videos yet retain pretty good quality? Thanks!
