> I have been having similar issues after a .26 upgrade and my profile is like yours - OTA ATSC recordings converted by handbrake's cli which used to make it through commflag --rebuild but since the upgrade don't. I only have the problem with shows from CBS and The CW which, in my area, are owned by the same company. In my case the seektable rebuild completes but myth shows the recordings to be exactly half their true length. The entire recording is there, I can see it using mplayer, but myth pops out after it gets to the 50% that it thinks is the end of the recording.
> The other bit of info I would add is CBS seems to be the only network that changes framerates during program/commercial transitions so my guess is there is some sort of weird interaction happening between the original material, handbrake, and mythcommflag. I only did the 0.26 upgrade a few days ago and haven't had much time to look into this but it's definitely an unwelcome feature.

Do you have an HD Homerun? I've been having it with a few different
channels. PBS, OMNI in Toronto, NBC Buffalo
