I do get the odd failed livetv tuning. the FE will claim it's playing in the 'info' OSD and the total play time will increase, but act like it's paused with a completely black screen when it initially enters livetv and the current position time stuck at 0:00.
thats basically what i'm trying to fix, so i'm looking at each Error or Warning message as they appear in the FE log. The DTVSigMon Wrong PMT message shows more often than the livetv playback issue, but since both occur at initial LiveTV tuning, i figured this could be related.
