As Mike has already said, you'll definitely need to get your hands on
the very latest 0.24-fixes - which had its latest livetv related fix
just a couple of hours ago. There's not really a lot that any dev can
do to help out if you're not on something pretty recent as there have
been so many fixes that any debugging of an older version is likely to
be next to useless.

If you can update and you still see problems, then please capture some
logs with '-v playback,file,record' verbosity for both the frontend
and backend (at the same time).
