I've been really bad at posting again... Since I last did post, I've managed to hit near PVR-utopia! I've managed to get it working pretty perfectly under Vista64, with the sat card picking up all the UK FTA channels and have also managed to work out how to pick up the Irish DTT signals for the 4 national channels. It's working almost perfectly at 720p50 including DVD playback with menu highlighting. I had to download a DVBscanner to get the Irish channels as it didn't pick them up on a normal scan. The telly found them so I knew it wasn't a signal issue. Turns out that the 3 rock transmitter is +166Khz out on channel 54. Must be a known thing as the DVBscanner included an option for scanning all channels +/- 166Khz. I then took the results, manually added the settings to GBVPR and bingo. So I have a dual Sat/DTT, 750GB web programable PVR with in theory 14 days EPG. I need to get Blu-ray playback working with the remote from within GBPVR and also 1080p50 sorted, but generally I am very pleased with how it's working now. Worth the upgrade!
