I don't have this card so this is just a guess, but this is what I  
would do:
Set it up as two separate cards and get them working independently  
(one as analog, one as digital - grab listing for analog, scan for  
Then assign them to the same input group so MythTV knows it can't use  
them simultaneously. That should get you a littler closer, anyway.
