cxm0: encoder dma not enough buffer space free

[Hansa]

I've set up pvrxxx for my PVR-500 card.

# pvr250-setchannel -d 0 -m 4 184.00
ioctl( tfd, BT848_GAUDIO ) failed.: Device not configured

When grabbing output to a file the folowing message is displayed in
/var/log/messages:

 # cat /dev/cxm0 > test.mpg
 Wait 1 minute...
 Hit ctrl-C
 # tail /var/log/messages
 cxm0: encoder dma not enough buffer space free
 cxm0: encoder dma not already in progress
 ...

Why is this hapening and what can I do about it?

Best regards,

Hansa
