[mythtv-users] Video dies every few hours

I am new to MythTV, and have a weird problem that has beaten me so far.  
I am using MythTV 0.19 on Ubuntu 5.10 with a Hauppauge PVR-150 - set up 
using Daniel Hyams superb instructions 
(hyams.webhop.net/mythtv/myth_ubuntu.html).  Initially everything works 
just fine, but after I leave the backend running for about 4-6 hours the 
video dies.  All I get if I try to watch live TV is a black screen, and 
any scheduled recordings lock up the card for the duration of the 
recording but end up by just generating a few seconds of the black 
screen.  When this happens if I try to use Mplayer to watch the video 
device I get the message:

    Playing /dev/video0.
    Cache fill:   0.00% (0 bytes)
    Exiting... (Quit)

After this I can't play video until I reboot the computer, whereupon 
everything works again - for another few hours.  I can't see anything 
suspicious in dmesg or /var/log/messages.

Any ideas would be very gratefully received.
