Which drivers are you using for the HVR3000?

I've got one of those cards working fine with DVB-S on Mythtv, using Astra
28.2E (from the UK).  I'm using Steven Toth's drivers from
http://linuxtv.org/hg/~stoth/hvr3000/

I did have some trouble getting any channels at all in Myth, but I can't
remember why now !  It was about 10 months ago that I got it all working.

I'm pretty sure that my setup also reports about 5% signal strength in
Myth - this is just a driver issue - it doesn't report signal strength
properly - doesn't make any difference to me.

I don't remember having to setup anything to do with a 22Khz tone in myth.

Can you lock onto the channels using szap ?  If you can do that, I think
it should work in Myth.

Robert.
