Yeah, extra frontends don't matter for recording.

I think this channel is 'refreshing' it's PSIP tables improperly,
as indicated by the discontinuities on the PMT tables, but we
shouldn't be failing when this happens.

Which supports the transmitter problem theory.

PAT and PMT are required for all MPEG recordings. Additionally,
the MGT and VCT are required for ATSC recording and the SDT is
required for DVB recording. You are making an ATSC recording
so the SDT doesn't matter in your case.

I think I'm going to have to look at this and make you a patch or
two to try. I'll try to find time for this next week.
