Did you get the blue screen on /dev/video1? I could only get /dev/video0 
working. Also don't switch an input between DVB and analogue as I found 
this causes some sort of hardware/driver screw-up. So if you want both 
DVB and analogue I think you'll need /dev/dvb/frontend1 and /dev/video0 
set up and connected.
