I asked this question internally with the other Moovida guys as it would be one of the BIG things from stopping me using Moovida. Which is a bold thing to say as I designed the SOB and nearly died one week finishing it all up lol.
Anyway, all things are possible and it is related to playback. Playback is a big 'theme' internally as we know we have to greatly improve on that. (being totally honest...our 'player' aint so hot). On the Plex media center project (Mac app), they do something very clever and they actually transcode all audio into an AC3 stream so your reciever can recognise it. Which is pretty useful for people who downlaod movies from iTunes which have AAC audio as an example...it gets pushed to the reciever in realtime and you get your 5.1 surround. (Yes, iTunes video content is DRM protected so they leverage Quicktime for that and step outside FFMPEG). I think I have these details correct... Im a lowly designer. :p Anyway, I think it is an issue that needs raising again. Launch a bug.
