In case anybody comes across this thread looking for answers, I seem to have resolved most of my problems. The key appears to be in getting the channel scan correct. I ultimately did the channel scan pretty much as directed in the HDHomerun installation instructions but then I entered the xmlvids myself. I didn't use the channel editor in mythtv-setup (that seems pretty tedious). Instead, I used the channel editor in MythWeb. Once I got the xmlvids correct things seemed to fall into place. A follow up mythfilldatabase seemed to do the trick (I can't remember if I used --refresh-all or just --delete).
<br><br>Note that I did eventually upgrade to the SVN version (0.20-fixes branch) because I eventually got QAM going on the other tuner. Now that I've got it figured out, it all seems to work quite reliably. It is quite sweet having one analog capture device, one OTA capture device and one QAM capture device. All in all, I think the HDHomerun is a great piece of hardware for the MythTV crowd.
<br><br>P.S. - To get the xmlvids I followed somebody else's advice on this list about using <a href="http://www.zap2it.com">www.zap2it.com</a> (not <a href="http://labs.zap2it.com">labs.zap2it.com</a>) to grab the 'stnNumber' out of the URLs and use those as my xmlvids. You'll have to find the detailed instructions on the mailing list somewhere.

Sorry, can't really help you as both the tuners on my HDHR work great,<br>one OTA and one QAM. Have you tried the SiliconDust forum? Jafa is quite<br>helpful there, although I know he is on this list as well.</blockquote>
</span><div><br>Yes, I've gotten one response from Jafa over there (still waiting for a response on my latest info). I posted here simply because it could also be a MythTV bug or something (hence the logs). I just hope I don't have bad hardware. I probably messed something up during configuration. The problem is there aren't any diagnostic messages explaining why the backend is crashing.
<br><br>I should probably try to generate a gdb stack trace. I don't know how to do that so I'll have to do some digging (at a minimum).<br> </div></div></blockquote><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
