Hi guys, I'm in the process of backing up my DVDs for archiving and already have a PS3. I am looking into buying an Apple TV but need a little guidance. I am intent on encoding my video files into a format that can support: a) chapter selection b) multi channel audio c) multiple audio tracks d) subtitles As far as I know the only format that supports the above is .mkv rather than m4v (which i assume is the Apple TV format). Does the Apple TV have the capabilities to support the above or should I stick with the PS3? Cheers, Marcel.
