[mythtv-users] HDPVR unable to record after upgrading to r20007 - in trunk

[John Hoyt]

Hi,

I just tried to upgrad to r20007 in trunk with the latest
DeviceReadBuffer-polltimeout.2.patch and hdpvr_audio_codec_selection.diff
patches applied.  When I swapped to live tv to test the latest build, my
mythbackend crashed.  Here is the relevant mythbackend log output:

Since the latest build wasn't working, I tried rolling back to a previous
build (r19988), after I unloaded and reloaded the HDPVR modules and verified
that the HDPVR was still working outside of mythtv.  To my chagrin, my HDPVR
still would not record in mythtv providing similar error outputs from
mythbackend:

The only guess I can wager on what's causing the problem is that the
"hdpvr_audio_codec_selection.diff" patch added new audio codec types to
mpegrecorder as well as added flags for them in the recording profiles
database.  Does anyone have a suggestion on how I might be able to get my
HDPVR back up and running through mythtv?

Thanks!
