I am looking to set up a multi room AV system in my house as I have the floors up for another reason so seems like a good time to do it! I have an amp which can do powered multizone audio, and a media network system which I can distribute audio and video through. I have an MCE box which will have my music / TV etc. What I cant get my head around is whether it is possible to play different video / audio in different rooms using MCE, without an extender. Making the assumption that I would want 2 different things playing simultaneously, eg 2 audio tracks, 2 videos from hard disk, does anyone know if this is possible and with what hardware / software?
