That did it!
I still get all the kernel error messages when loading the cxm module, 
but pvr250-setchannel now only gives the audio error when tuning by 
frequency. Tuning by channel number still produces the invalid argument 
error.

When tuning by frequency I get a very fine result testing with

#cat /dev/cxm0 > test.mpg

Thank you very much for you assistance! I will be more than delighted to 
help you test any patches/fixes you come up with, if you need it.

Best,
Simon
