OK, I have a PC, with 4 Xboxs linked to it through a switch acting as media centre extenders. With this setup I can view any of the media on the PC through any of the Xboxs. I want to add a TV card to the PC. I would like to have a 4 channel TV card, allowing each one of the Xboxs to have a dedicated TV stream from the PC. I am using Vista's media centre. Is this possible, and can someone please recommend a TV card for UK use that can do this. I'd lso be grateful if people would share their experience of this if they have any. Many thanks.
