[mythtv] "waiting for free video buffers timed out" with backtrace info

After watching about 20-30 minutes of a pre-recorded show or live tv, 
audio stops and the video freezes.  Mythfrontend repeats "waiting for 
free video buffers timed out" over and over again.  You can find the 
output of my gdb backtrace following this message.

I can recover by doing a "kill -9" on my X process and starting 
mythfrontend again.

I am using the CVS from 4/14/04 8:45PM ET.

If it's any help, here is my setup:

- Shuttle XPC Barebone System for Socket A at 400MHz FSB AMD CPU, 
Silver Model SN41G2V2
- AMD Athlon XP 3200+ "Barton", 400MHz FSB, 512K Cache Processor
- Corsair Value Select (Dual Pack) 184 Pin 1G(512MBx2) DDR PC-3200
- Maxtor 250GB 7200RPM IDE Hard Drive, Model 7Y250P0
- NEC 8X Silver DVD+RW/-RW Drive, Model ND-2500A
- Hauppauge PCI Video Recorder, TV/FM Tuner Card, Model "WinTV PVR 350"

Thank you,

Spmc
