[mythtv-users] Mythfrontend freezing/crashing watching SD or HD LiveTV

Hi,
Recently I got my comcast firewire box to communicate with my mythbox --
and quite a few channels are now *working*. Since I wanted to see how
well things work, I did some watching via livetv (which I normally don't
do). After some amount of time watching a SD channel (like 30+ minutes)
the picture will freeze up and my computer will become noticeably busy.
I noted the following error messages:
prebuffer wait timed out 10 times
writeaudio buffer underrun
prebuffer pause
timed out waiting for free video buffers
Shortly after the "video buffers" errors the X session will crash.
I have searched google and the mailing list, but the only thing I found
on the last error was here:
http://www.gossamer-threads.com/lists/mythtv/users/266458?search_string=video%20buffers;#266458
however, no solution (other than turn of glx) was suggested. I really
want 3d graphics, so I want to put that off for the last resort.
For the "prebuffer pause" I found suggestions of adding "noapic" to the
kernel bootup (I use grub).
The writeaudio search only resulted in this discussion:
http://www.gossamer-threads.com/lists/mythtv/users/121403?search_string=writeaudio%20underrun;#121403
Which is a little dated....
So, I am looking for any hints of things I may have missed. Any help is
greatly appreciated.
