Hi John;

You're not alone.

I have three tuners, a dual tuner HVR-1600 used for OTA ATSC/Analog
Cable and an HVR-1250 also used for OTA ATSC.

Like you, my Analog recordings get flagged and skipped as expected,
but some ATSC commercials aren't skipped.

This is done on an mythbuntu 9.04 system running trunk at 23743M.

I don't have the answer, but here's a sample case.  The 1st commercial
is not skipped.  In the following, note that the job queue correctly
reports that there were 4 commercial breaks.

In the recordedmarkup, there are some entries that don't have sequential
commercial start/end pairs -- they're flagged below.  I don't know if
this is normal, but I've not noticed it before.

mythfrontend was run with -verbose general,important,commflag and is
available at http://pastebin.ca/1846334.  mythcommflag was also run
manually, output at same pastbin.  Logo for this show was in the lower
left.
