To "scan for channels" you are asking the tuner to find out which channels it 
can see. The only channel your pvr150 can see will probably be 3 (see above). 
You are not connecting myth directly to your stb, so it can't tune the stb. If 
you want to do that, you'll have to investigate firewire.

What you are doing now should be fine, but you'll also have to get an IR blaster 
so that myth can change the channel on the set top box. You'd get a better 
signal quality if you used an s-video cable from stb to pvr150 instead of coax.

You don't have to scan for channels in any case, if you're using Schedules Direct.
