I am not sure what I am doing wrong, but I set up my PCTV to Go HD with Media Center and when I click on Live TV it works perfectly.  The guide works and I can change the channels perfectly...but my issue is when I try to record something I get the error "there is no tv signal" even though I'm watching it Live....when I try to schedule a program to record I get "there was no tv signal when the show was scheduled to record." Has anybody had this issue or any guesses as to what the problem might be? Thanks.
