I am getting a similar problem with an HDHomeRun. I don't get this exact
message, but I do get seemingly random recording failures that result in
0-byte files. If I don't cancel the recording right away I'll get
hundreds of thousands of lines of log output like this:

2007-02-10 23:29:38.966 HDHRRec(3): AdjustFilters() no pmt or no pat
2007-02-10 23:29:38.972 HDHRRec(3): Resetting Demux Filters

It only seems to affect ATSC stations. The regular MPEG stations (I am
using Comcast Cable) never have this problem. It has occured on multiple
ATSC stations including local affiliates for FOX, NBC and CBS.

Tonight I upgraded to svn 12770 from 12640 to see if it got any better.
It failed on my first scheduled recording (tonight's SNL). I had to
cancel and restart the recording 4 times before it finally started
recording correctly.

Verbose log output is attached for the first failed attempt. The entire
log including the 3 failures and the final successful recording is about
400k if anyone wants me to send it privately.
