Hve you tried using the dvb-apps and scanning for your channels?

I have had problems with the myth scanner not prodicuing any output. I 
had to use the long route which is:

You have to either a) know what the dtv_multiplex, serviceid and 
xmltvids are for your channels, or b) have a channels.conf which 
contains enough of that info for myth to figure it out and put the right 
stuff in the right places, so mythfilldatabase can complete things.

So (and all of this is on the wiki). get the dvb-apps.
Run atscscan -c US-Cable-Standard-Frequencies-QAM256 -a 0 -f 0 -d 0 or 
whatever is required for your setup, and grab the output. This is a raw 

Using azap to tune a partciualr channel+serviceid combo, use mplayer to 
see if it is a watchable channel. Delete if not. This produces a real 
channels.conf which can be (if yoo are lucky) imported into myth.

At present, you probably get nothing, because your card is tuned to nothing.
