Handbrake / VLC work perfectly on my MBP to rip DVDs to m4v files, but my brother's MBP is not working right. DVD appears to rip correctly, although slowly and a very large file size A typical DVD ripped at AppleTV 2 setting on my computer is about 1 - 2 MB, on his it came out to almost 6 MB. However, when you try to play it back, it is horribly blocky and garbled and the sound is very choppy. You can't see the picture at all. At first, I thought there was a problem with Handbrake, but upon further review, I tried to play the DVD in VLC and it looked the same way, so I am assuming that the problem is with VLC's decrypting. So what gives? Anyone encountered this before? THANKS!
