We just install a Dish DVR systems that allows one box to control the video in two rooms. Great so far. But I also have Comcast. The one coaxial input on the back of the Sony Wega is taken by the Satellite. How can I get the second coaxial cable from comcast into the set as well. Yes I know I could run them thru a vcr, or dvd recorder, but is there any way to avoid that. Thank You, Adam
