I forgot to mention above that once the card is able to get a lock, it 
continues to work correctly until I reboot the machine.  As I type this, 
I am viewing an mpeg stream.... The machine has been left powered on for 
the past 36 hours or so...maybe longer.  This confirms that my 
intermittent problem is NOT a heating issue, (and the fact the i dont 
have the problem in windows).

Attached is output from mplayer.....  Maybe this can help to explain my 
situation where the ts stream lasts for a short time.  On some channels 
I can get a stream lasting many minutes, and on other channels, the 
stream only holds for a few seconds.....  I have gotten better results 
using xine, but I figured posting this output could help to explain my 
situation.

I thought this might have been a mplayer problem, but proved myself 
wrong when I fed mplayer a saved HD .ts stream that I captured from the 
windows software.  It worked perfectly with no such errors as below:
