I think you should use the DVB driver, don't worry about testing it with
another program, if it's working myth will recognise it when you select
the right card type in mythtvsetup and allow you to scan for channels.
One tip though, make sure mythbackend is not running when you set the
card up in mythtv, or else it won't be able to scan for channels, the
card will be busy.

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.
