[mythtv-users] Problem controlling external tuners in new upgrade using mythtv V0.25.3

[Craig Huff]

Sad to report that deleting all capture cards and, as a consequence all
input connections, followed by recreating them all, did not solve or modify
the problem I'm having.  Stations still get tuned to successfully on
startup, but attempts to change them while in Live TV mode (attempted on
multiple tuners) fails to resync video (my term -- screen goes black and
eventually the FE comes back reporting "Video frame buffering failed too
many times" and exits the Live TV mode.

Here again are links to pastebins of mythbackend.log
<http://paste.ubuntu.com/7517206/>, mythfrontend.log
<http://paste.ubuntu.com/7517203/>, mythmetadatalookup.log
<http://paste.ubuntu.com/7517205/>, and mythpreviewgen.log
<http://paste.ubuntu.com/7517204/>, if someone thinks they can figure out
something by reading their contents.

For reference, here are rough event times relevant to the logs:
16:55:45 Started mythbackend
16:56:05 Attempted tuning to channel 160, briefly got the "Signal %0 | (_L)
Lock" message --
              maybe 5-10 seconds and got tuned (apparently) but with black
screen (no video
              displayed, but audio output working)
16:56:20 Attempted tuning to channel 475, got the "Signal %0 | (_L) Lock"
message and no
              updates for over 20 seconds
16:57:14 Quit with the "Video frame buffering failed too many times"
message.

I then exited from all the myth*** and pastebin'd the logfiles linked above.
