I've just got an XBOX (at last!) and I've got it hooked up to my plasma screen via composite (not great I know), the quality is not too bad but obviously I could get alot better if I went via component connections. I understand you can get an advanced AV pack which has component video out and an optical out for the Dolby 5.1 sound, but I am having trouble finding a good place to get it on line. Does anyone know of anywhere I can get one of these AV packs and roughly how much they cost?? Many thanks in advance for any help.
