Music is usually played on the CD player, but can be streamed wirelessly across from the PC via iTunes to the small Airport device plugged in to the AUX input on the preamp (actually comes in handy more than you'd imagine). The Xbox 360, Sky+ and Sony DVD player are all hooked up to the Viewsonic Projector via a variety of leads, but the end result means it's easy enough to switch between these with a press of a single remote!
There is a pulldown 60 inch x 60 inch screen which I mounted on blocks of wood above my cupboard doors. Handy to store away (rollable) and is actually not that noticable when fully folded away - took some calculating when mounting the projector, otherwise went smoothly
I'd say the next thing to buy is a nicer DVD surround sound setup, as this is ageing, and then eventually upgrade the TV when Sky HD rears its head
