Ken,

I don't know what's up with that, but I've attached two patches that 
might help.

First, if you just want to get rid of the error message use 
"simplefix.patch".  It changes the log message from IMPORTANT to RECORD 
so it won't be printed out.

Second, if you're good with tools and want a better look at the 
recording process, use "134-hdhr.recstats.trunk.9.patch".  It logs the 
HDHR statistics at the end of the recording.  You'll get lines like this:

    2009-07-14 11:23:30.801 HDHRRec(41): HDHR Stats: pkts=219453 hwm=215 
KB Errors: net=0 trnsprt=0 seq=0 ovflow=0
    2009-07-14 11:25:27.357 HDHRRec(43): HDHR Stats: pkts=122871 hwm=215 
KB Errors: net=0 trnsprt=0 seq=0 ovflow=0

These stats are directly from the HDHR library and display counts of 
net, transport and sequence errors, as well as internal buffer 
overflows.  I don't really know what they mean, but smaller number are 
better (you should check the hdhomerun docs for specifics).  Any 
significant non-zero values generally mean missing or corrupt data, 
either of which could result in your original error.

Two caveats.  These stats don't work for liveTV, and I use fixes, so the 
134 patch might be a little flaky but it should work and shouldn't hurt 
anything.
