I have two of these cards. They work great, but it took me a long time 
to figure out how they work in MythTV.

I use Schedules direct, and I didn't know that I needed to add a lineup. 
That could be one issue, but if you got it working with an different 
tuner, you might need to add that Local Broadcast source.

The other issue was that I had to set a beginning channel, after I did 
the scan. mythtv-setup warned me about not having it set, and I don't 
know if that would be an issue since you are adding to an existing setup.

I wouldn't expect snow at all from a digital OTA signal, it's on or off, 
so if you're not getting a lock (mythtv will tell you) and if it is 
weak, the picture just goes blocky, no snow... maybe you're tuning 
analog... I don't know how to force one tuner vs. another, but my setup 
is two OTA tuners only, so maybe you're tuning an analog station, rather 
than a digital one.

I'm still a MythTV noob, but hopefully, that helps, or springs to mind a 
solution from someone more knowledgeable.
