Patching mythtv is certainly one solution here, but in the end that recording (and it sounds like anything captured from that channel) is most definitely messed up and should be fixed as well. 

I've been doing my editing in a VM, but transcoding may well be the answer.
I'll investigate. A lossless cut is NOT the answer, a byte by byte rebuild is what is needed (ideas anyone)(ffmpeg ??).

BTW I'm 10 km from transmitter site, with a professionally installed multi-element external antenna running type N cable by a clueless tech who had no idea of the effect of "another access plug"

But the problem is not limited to a single channel, but interestingly all the 200MHz channels (OK 186, 223 etc) have an issue, the 500MHz did not.
