Hi! i wanted to know is there any way i can use my single HD tv to run xbox and ps3 through hdmi, even though it only has one hdmi input? i dont want to have to go switching cables all the time, its awkward! i thought maybe there would be a hdmi cable, like those ipod headphone cables which you can plug in two sets of headphones, but for plugging in two hdmi cables so that i can then plug them both into my hdmi port? obviously i wont be running both systems at the same time, but it would save on crawling around repositioning cables? thanks
