Hi,
I'm running a new install of 0.20 on Ubuntu 6.10. I installed this via apt-get.
After a few hours of playing live TV I sometimes get the error:-

"Error was encountered while displaying video"

I've no idea why this happens, I'm testing the box with a view to
replacing my Tivo so I'm trying to iron out the bugs before moving it
in to the lounge!
I have two WinTV Nova cards in the box.
When it happened just now I managed to get the last few lines of the
/var/log/mythtv/mythbackend.log file:-

The box is running an AMD Athlon64 3200, 1gb ram and a Seagate 7200rpm
200gb disk.

Any clues as to why this happens every few hours?

thanks
