[QUOTE="Peter Mee, post: 1042828, member: 143574"] So I figured this out and thought I'd post for future head scratchers.... I managed to obtain a TV with DVB-T tuner to try to establish if I had a signal or hardware problem. Plugged in the TV, hit auto-tune and ended up with all channels across 2x multiplexes (30 & 58) set up perfectly with 100% signal and quality levels. Since my issue was only with channels on multiplex 30, I looked at that in more detail. Those channels on the TV were coming in at frequency 542MHz. When I checked the same channels on MP, they were tuned on 778MHz (multiplex 58 is on 770MHz). I manually changed the frequency for all of the problem channels (778 -> 542) and they displayed perfectly. So, is it the case the MP tunes to the highest/last frequency a channel appears at, even if channels are present on lower frequencies with better signal strength & quality? Will I need to make this manual alteration whenever I need to retune? (now I need to figure out why my DVB-S2 tuner has disappeared from my system - must have knocked something out of whack...)
