Hi, I've aPVR-9300T. If I set ITV1 to record and then go to BBC1, BBC1 is breaking up/freezing/blocky. If I stop the recording and go back to BBC1 all is well. If I set BBC2 to record and go to BBC1 all is well. Is this something to do with the 2nd tuner and the BBC channels all being on one MUX? I'm going to do some more testing to see if I can find a common denominator. It always seems to be the BBC channels that break up rather than any others. Thanks.
