One digital channel not working

[split]

I have GBPVR setup with a hdhomerun using qam from the cable and initially everything worked fine. For the last week i have one channel that will not tune in through gbpvr. I can tune this channel with vlc that came with the hdhomerun but not in gbpvr. Within gbpvr i get the no signal detected message and the quality and strength bars. The quality bar is probably around 95% and the strength 85%. When i am tuning the channel through VLC it shows the following numbers in the hdhomerun app. Signal strength 91% signal quality 96% and symbol quality 100%. This is the only channel i cannot tune in gbpvr that the hdhomerun picked up. The channel is 56-4 in the hdhomerun remapped to 80-3 (dsc). Any help is greatly appretiated and the logs are attached.

Have you tried rescanning for channels? Its possible the PIDs for that channel have changed, and no longer match the set that were found when you scanned in the past.

Thanks for the help, that was the problem. I am still trying to get my head around all of these different numbers. Both the tv's tuner and the VLC player that came with the hdhomerun were unaffected so i am not sure how that happens.
