Thanks Ace987, I was about to take my ReplayTV back to Radio Shack after spending all evening trying to get the IR blaster to stop sending out 3 of each numbers. I foolishly set it to a program and went to walk the dogs after doing the initial setup, only to return to find I'd missed the first part of my show because instead of channel 72, it put it 000 777 222 and got a channell I don't subscribe to. As I stayed up past my bed time, trying every set up, I had come to the conclusion that I would have to take it back and just settle for a VCR.
Then I woke up early, after dreaming about my ReplayTV all night long, with the idea to search the internet and I came upon this post, tried the Customer Service guy's numbers and then tried yours Ace987. I almost cried as my ReplayTV went right to the correct channel each time.
Thank you, thank you so much!
