Take a look at this thread:


Sounds like you might have the same problem.

I think the long term answer is to figure out how to use the dvb  
drivers.  I'm still using the v4l drivers with my hd-3000, because  
that's what I got working first and haven't taken the time to get the  
dvb drivers working.  I've had difficulty like you have with them, but  
I honestly haven't spent much time on it.
