The OP is clearly not in the USA. I don't know what the over-the-are situation 
is in the Netherlands, but it's entirely possible he has some UHF analog 
channels available.

Even here in the USA there are still a lot of analog channels available on 
cable systems, though I agree most systems are moving away from them. I 
receive over 60 analog channels, and my PVRs are still useful, for now at

Maybe even firewire, but again I have no idea what's available in the

AFAIK none of the above situations supports channel scanning by Myth, so we 
need to find out what the OP's signal source is, then we can offer some 
(hopefully) useful advice.
