I'll try to give the exact errors per event. This is what I got tonight when a scheduled recording failed...this is the backend log:<div><br></div><div><div>2010-02-22 18:21:04.955 UPnpMedia: BuildMediaMap VIDEO scan starting in :/var/lib/mythtv/videos:</div>

<br>But then (a few days later) I lost ability on my other tuner with the "Excessive channel retries" error showing up repeatedly. After a restarting mythtv-backend, rebooting, and resetting the directv box it finally came back. I would get the same "Irrecoverable error" showing on the screen when tryint to change <br>
channels. This time I got a good chunk of interesting errors, most of which I've seen before but couldn't figure out. The first line had repeated multiple times, I think from when I tried changing a channel when on live tv:<br>

2010-02-27 14:19:41.998 scheduler: Finished recording: The King of Queens "Dog Shelter": channel 1247<br><br>So there is probably a good capture of the errors I have seen while trying to figure this problem out. Periodically the tuners will lose connection and throw the "excessive retries" error. At that point the only way to recover is to unplug the usb connection that connects the directv box <br>
to the computer. Then resetting the directv box a couple times until it grabs the connection again. Strange.<br></div>

</div>What does the mythbackend log say went wrong at the time this failed? If<br>
it is an error from the directv script like the retry message we need to<br>
try changing both the myth external channel change command to verbose and<br>
then try the same from the command line to try to figure out why they act<br>
different.<br>

><br>
</div>You may have more than one problem. Does the backend log have channel<br>
change errors at this time or is it a different error? Does the front end<br>
messages say anything useful? I wouldn't expect the connection problem to be<br>
related to the directv script.<br>
<br>
The exact error messages are important for trying to track down the problem<br>

</div>I have seen this on my system also. I see it as a static picture of the<br>
wrong channel before the correct video starts displaying. It isn't coming<br>
from my box. I assume myth is reusing old data but I have not looked into<br>
it since it doesn't seem to cause problems.<br>
