Hi Matthias,

I have this same problem with 0.19-fixes svn. I have a DVB-T setup,
whenever
I watch livetv I see the video subtly alternate between slow and
fast play. I mentioned
this on the #mythtv-users irc channel, a while back, and someone
responded that it
was a known issue among the developers, but no-one had managed to
track it
down. The work around, they said, was to pause and then unpause livetv.
This works perfectly for me. Note that my system is a single
backend/frontend
box. It's only a slight annoyance.
Cheers,
Doug
