Thanks for your quick reply!
I just have the MTS classic tv. It's a black motorala box and I can have up to 3 tv's on it.
I just want to use my computer as an extra tv screen. Our main TV is in the family room in the basement and we can't afford another tv upstairs. The Acer computer I just bought came with a tv tuner already inside, so I thought this would be a way to get an extra tv. I'm not sure how to change the PC tuner to channel 4, 8 or 11.
The tv tuner for my computer came with a wireless antenna and it's own IR blaster that is supposed to plug into the computer. So I was trying to use the Acer IR blaster to set up the tv tuner.
