So long, of course, as you don't want to record two different things at the same 
time. Only one input ie tuner, s-video, composite, can be selected at one time 
on any one card. OK myth will switch between them as appropriate, but you can't 
record from more than one at any time.

If you are using s-video to connect the set-top-box, you can get any cheap card 
to feed the input into myth. Much easier (and how the system is designed to 
work!) than messing around with hardware switches. Not to mention limiting your 
recording options.
