On Friday night I set Gardeners World and Parades End to record ( both on BBC2 HD on ch 54 ). When I came to watch GW a message flashed up saying recording failed - no signal. At first I assumed some sort of transmission failure but instead of the blank screen I would have expected I was asked if I wanted to watch anyway. It had recorded 23 mins of the paralympics ( yawn ) preceding GW. Curiously Parades End was recorded OK but on some channel in the 1000+ range - it included the last 5 mins of GW ( I add padding ). Was this a case of the preceding programme overrunning and no epg update being sent - ie tough luck, it's out of my control. Or is it something I can avoid in future? BTW I did use automatic tuning and clearly do receive from two transmitters. It used to be necessary to get good reception on all stations but probably isn't now. It never bother my previous PVR but I understand it may cause issues with the HDR.
