Not sure if this message got lost, also not sure where. Anyway after a
lot more poking around on the internet, Discovered a patch for v4l
which meant recompile v4l from source.

I'm now running Mythbuntu 64bit with a patched version of v4l (must
take a note of where I got the patch from!)

This patch creates two dvb frontends in the same adapter folder, which
work fine in kaffine but not in myth. Ie both tuners turn up in
/dev/dvb/adapter0, first one ending in 0 (thats the satelite one) and
second ending in 1 (thats the Terrestrial one) eg
/dev/dvd/adapter0/demux1

In Myth it works if I first hmm

mkdir /dev/dvb/adapter1
ln -s /dev/dvb/adapter0/demux1 /dev/dvb/adapter1/demux0
ln -s /dev/dvb/adapter0/dvr1 /dev/dvb/adapter1/dvr0
ln -s /dev/dvb/adapter0/net1 /dev/dvb/adapter1/net1
ln -s /dev/dvb/adapter0/frontend1 /dev/dvb/adapter1/frontend0

Myth can then be restarted and works. (So long as you don't try and
use the satellite tune at the same time (Don't have a sat so don't
care)

How do I tell udev to do this automatically. I think this is strictly
a bug in Myth that it can't cope with dvb cards with multiple
frontends (dvb frontends not to be confused with Myth frontends they
are completely different)

Oh its a HVR3000 tri-tuner card is that helps

Peter.
