For some reason unknown to me, the udev er.. thingy that creates the 
devices tree under /dev doesn't quite work properly for dvb devices.  In 
kernel 2.6.10 I still used devfs, but I took the plunge & did away with 
the deprecated system (not sure I had a choice exactly).

I had the same problem you're having when I built a new system to 
upgrade the backend using kernel 2.6.12.whatever

I searched on google for ages & saw something about the udev rules.  I 
had a look at the rules config file & saw pretty scary stuff (to my eyes 
anyway).

It was then I tried coldplug & hotplug.  I'm not sure hotplug made a 
difference, but you can try it.  Here's the result of me doing
rc-update -s  (with the non-running services deleted to save space).

               webmin |      default
                  xdm |      default

This is from using a stage3 install mind you...

Oh - and check that the kernel modules for the DVB card are being loaded 
at boot time (i.e. that they're in /etc/modules.autoload.d/kernel-2.6) 
BEFORE mythbackend starts up - that can cause problems too.

What I always recommend you do is get the hardware working and verify 
it's working BEFORE even going into mythtv.  That way you know which is 
to blame (and it's never myth).
