Try typing two commands:
	$  cat /dev/cxm0 > test.mpg &
	$  mplayer test.mpg

Also, it's saying the device is busy-- perhaps another process has the
device open?

If you've tried the command recently and no new lines appeared in your
messages, then the cat is not related to the error messages.

Ah, I'll have to try the cache option.  Do you really need 8 MB of cache
for it to work correctly?  What's the minimum cache amount before mplayer
starts having the seek failure?

So far you've proved exactly what I was saying before.

I think the dmesg errors you pasted before have nothing to do with the
seek problem.
