<div>Before attempting to get them working in Myth, I would validate that they work outside of Myth using the standard hdhomerun commands. Per the above I would do :</div>
<div> </div>
<div>hdhomerun_config ffffffff set /tuner0/channel qam64:81</div>
<div>hdhomerun_config ffffffff set /tuner0/program 1</div>
<div>hdhomerun_config ffffffff save 0 test.mpg</div>
<div>mplayer (or whatever you prefer) test.mpg</div>
<div> </div>
<div>Change the program in the second line to go through all 8 programs. That will validate what is really there and what the hdhomerun can really see first.</div>
<div> </div>
<div>If that is all working, it would be good to get more debugging information from the backend with -v all to see what is going on.</div></div>
