[mythtv-users] recent SVN DVB LiveTV audio problems

[Robert Tsai]

This past weekend I've been having problems with LiveTV over-the-air
HDTV broadcasts on both FOX NFL (WFXT) and ABC Monday Night Football
(WCVB). I get the game audio, but no broadcasters' commentary. I am in
the Boston area. As far as I can tell, other broadcasts have been
fine. Is anyone else seeing this problem?

If I switch to record the broadcast and watch it in near-real-time,
then the audio is fine, so the problem is only with "LiveTV".

This is on a system running SVN current with an HD-3000 and ubuntu
hoary64.

All I can see is that the PID values are different, but I don't know
if that is important here ...
