<br>While watching Live TV, I can change channels successfully for any tuner using manual invocation of the appropriate tuning script in an open xterm. If I have made an external channel change, when I restart the Live TV mode, mythfrontend succeeds in changing the channel back to what it thought the last channel assignment was. However, things are different if I change the channel within mythfrontend by typing a channel number using numeric keys on the keyboard. When I do, the appropriate channel change script gets called and does it's thing, but most of the time (I just hate inconsistent results!), a message in the OSD display pane reports "Signal %0 | (_L) Lock" and eventually the frontend gives up, throws up a pop-up reporting "Video frame buffering failed too many times" and exits the Live TV mode. Here are links to pastebins of <a href="http://paste.ubuntu.com/7517206/">mythbackend.log</a>, <a href="http://paste.ubuntu.com/7517203/">mythfrontend.log</a>, <a href="http://paste.ubuntu.com/7517205/">mythmetadatalookup.log</a> <span id="goog_812516535"></span><span id="goog_812516536"></span>, and <a href="http://paste.ubuntu.com/7517204/">mythpreviewgen.log</a>, if someone thinks they can figure out something by reading their contents.<br>
<br>For reference, here are rough event times relevant to the logs:<br>16:55:45 Started mythbackend<br>16:56:05 Attempted tuning to channel 160, briefly got the "Signal %0 | (_L) Lock" message --<br> maybe 5-10 seconds and got tuned (apparently) but with black screen (no video<br>
displayed, but audio output working)<br>16:56:20 Attempted tuning to channel 475, got the "Signal %0 | (_L) Lock" message and no<br> updates for over 20 seconds<br>16:57:14 Quit with the "Video frame buffering failed too many times" message.<br>
<br>I then exited from all the myth*** and pastebin'd the logfiles linked above. I appreciate any help in getting to the bottom of this wierdness.<br><br>--<br>Craig.<br></div>
