You're correct that you'd need to set up different sources, but I'm pretty 
sure you don't need separate cards for that. In MythTV, sources are linked to 
INPUTS, not CARDS. So long as a card has multiple inputs, such as coax and 
S-video, you can link each one to a different source. I've got a card 
(actually a USB encoder) that I use mostly for recording off of cable via 
coax, but I've also got a laserdisc player hooked up to its S-video input. 
There's no listings source associated with the laserdisc player, of course, 
but there could be, and MythTV certainly doesn't think I'm recording The 
Wheel of Fortune (or whatever) whenever I record input from the laserdisc
