I used 0.9.2. I didn't know what a developer snapshot was until a few hours ago when I downloaded one. I'm having trouble with that rip of The Simpsons Movie. About 5 minutes in, the video freezes, goes to B&W, and then the sound starts over at the beginning with the Fox music. If you skip forward a couple of minutes, everything else is fine. But I'm downloading all sorts of apps to try to get this to work (VLC, FairMount).
I also encoded the files with both the stereo and surround tracks.
If someone above was asking about if I was sure about using Dolby Digital, I just know that before I had the DD output off on the ATV. After I turned that on, the sound was a lot better and the "DD" logo came up on my receiver. It's not Blu-ray Disc-quality sound, but it's an improvement over stereo.
