I wasn't having any luck with the DSP on the 2.6.29 kernel (cmemk
problems) so I went back to 2.6.28 and I almost have it working, it
plays the video fine or 2-3 minutes, but then crashes and takes the
board down with it.
Any ideas?

****At this point the video plays with the TI watermark in the top
right corner with both sound and video, they appear to be insink...
However after about 2-3 minutes the video freezes, as does the USB
mouse and keyboard on the board as well. Using a terminal over serial
communication, I had 'top' running and the while the video is playing
it take up around 30% of the cpu, but once it freezes it shoots up to
99 then hovers in the 75%-99% range.
The mouse and keyboard remain locked up on the beagleboard, even after
the process is killed.
Perhaps the USB bus has gone down?? Could the warning about the clock
error be affecting the USB bus or it's clock?
Any suggestions are much appreciated
