My tv has one DVI input which at the moment has my dvd player connected to it. i want to connect my pc up to it too but don't want to be switching cables all the time. is it possible to buy a HDMI or DVI hub that will allow multiple devices to connect to a single HDMI or DVI input? did a search on google and all i could find was the Gefen HDMI splitter which does the opposite to what i want. Cheers.
