I'm running it on the Debian 2.6.18 kernel, viewing free channels (our 
provider Kommunicera gives us the standard channels via analog and 
unencrypted DVB-C).

Scanning still sucks for me, but since I did the initial scan using a 
borrowed DVB-C card (something 1500 something) I'm happy for the 
moment. It would be nice if scanning worked tho, then I might be able 
to run myth-setup to completion (currently I use mplayer combined with 
at to record programs).

I'd suggest you find someone that can provide you with a 
ComHem channels.conf to circumvent the scanning problem for now...

He said he will, I suspect he's just not had the time to do it.

  If turning it on doesn't help, plug it in.
