Paul, Barry,<br>
not adding anything helful I am afraid, but maybe related?
Recently I observed the problem tha occasionally, the audio of my
recordings gets tainted... I think the center channel in the
surround audio track gets lost, yesterday I had an example, some
sound but almost no voices.I switched the frontend audio to
hdmi/2.1, same, then in the playback, I switched from the surround
track (ac3 I think) to stereo and the voices were back.<br>

<p>Here during playback of some DVDs (old school! <joke>) we
have noticed sometimes the surround sound is not properly detected
so only plays 2CH (front channels). Sometimes a power cycle
brings it back, sometimes not. While this has nothing to do with
MythTV it seems to indicate sometimes the signal isn't correctly
determined. (Will see what happens when I add a Frontend after
the remodeling.)<br>

<p>Possibly nothing but I am wondering if when the surround sound
channels are lost if there is a problem with Closed Captioning?
Here have noticed some CC 'spelling' is really bad: parts of words
are missing or duplicated. Something like "the quick brown fox"
would be displayed as "the quin bro foxox" ==> 'quick' and
'brown' being smooched together, the 'ox' of 'fox' being
repeated. Thinking perhaps a slight corruption of the programme
-- thinking if you loose your surround sound plus a corruption of
the Closed Captioning text then perhaps is due to a problem in the
recording. (I'm only barely familiar with ATSC format here in the
U.S.; guessing you are in the EU and so PAL -- may not be the same
method of CC encoding.)<br>

suspected the problem in the programming or recording,
drivers...??? But not in myth. I guess I should try to reproduce
playing the file with with vlc.<br>

<p>Out of curiosity if you replay the segment with missing surround
sound audio does the same thing occur? Might indicate if the
problem is in the recording or was possibly due to a heavier load
on a processor at the time. I'll admit this is a guess.
Comparison via VLC is also a good thought: at least would help
determine if the problem was in the recording or the playback
process.<br>
