I did this also. Windows Media Center’s TV tuner will not recognize the channels that TV 2 come in on (mine is 73). Only channels channels 2-4. You could “capture” video using MovieMaker and tuning to channel 73, or you could do what I did, which was run TV 1 to the PC with a coaxial going from “TV 1 Out.” I have my TV 1 hooked up to the TV using RCA cables, so I’m not using the TV 1 Out jack for the TV. I was originally going to split my TV 2 cable, which goes to a TV right NEXT to the PC, but came across the channel issue which prevented watching “Live” TV and getting the program guides, etc.

If you can, give it a try with a second TV first and see if that part works If it works with a second TV, then it is a PC setup issue.

You can always call Dish support for help.

What message appears in your computer? You must properly check your tv tuner card if it’s working. Then you must have a software or driver for your tuner to work on media center.
