#2541: mythbackend segfault when attempting to record from hdhomerun using qam256

     Type:  defect            |      Status:  new    
 Priority:  minor             |   Milestone:  unknown
Component:  mythtv            |     Version:  0.20   
 Severity:  medium            |  
------------------------------+---------------------------------------------
 When mythbackend starts to record a program or an attempt is made to watch
 live tv on a hdhomerun capture device, mythbackend segfaults with my
 setup.  This is running svn trunk revision 11452.  I have verified that
 QAM tuning works on the device using hdhomerun_config to tune a valid
 clear QAM channel and viewing the udp stream using vlc.  8vsb
 viewing/recording also works fine from vlc as well as from myth; so it
 seems the device is funtioning properly.

 I have a working mythtv qam setup with an Avermedia A180, and I tried to
 assign the hdhomerun capture device the same videosource as the A180 which
 resulted in the segfault.  I also created a new videosource and performed
 a qam256 channel scan from mythtv-setup for the hdhomerun device (which
 worked fine), which still resulted in a segfault with attempts to record
 from the device.

 A mythbackend log from mythbackend ran using -v record,channel,siparser
 and a gdb backtrace when the segfault occurs is attached.  The backtrace
 is from mythbackend attempting to record a scheduled recording on the
 hdhomerun capture device.  Please let me know if any further info is
 needed.

 Thanks,
 Dwayne
