[linux-dvb] FusionHDTV DVB-T Dual Digital2

I've tried a few things over the last few days:

- I grabbed a channels.conf from one of my collegues who lives quite close to 
where I do, and configured mplayer to use it. No dice.

- Borrowed a similar tuner (DViCO FusionHDTV DVB-T USB usbid 0fe9:db11) and 
got that working no problems. Generated a conf from it, watched a couple of 
channels, etc so its definatly not a signal issue.

- Put the Dual Digital 2 back in and tried it with the newly generated conf; 
the card locked up again.

I'm starting to think it might be something to do with when its locking onto a 
signal. I'm probably going to put some kprobes into the kernel and see whats 
going on right before the lockup.

If you think it would be of some benefit, I can come onto IRC sometime and we 
can try and work out whats going on. What timezone are you in?
