Hm... This is a bit messy... You'd want the first card to have both sources to 
easily (or easier) change to digital channels for live TV (by toggling 
inputs), but then this card would be the first one used for recordings, so if 
something was recording, you wouldn't be able to watch the digital 
channels... I think you may have to wait for work to be completed on the 
patch that allows you to change between inputs and cards in one fell swoop to 
get everything working optimally... :-(

There ain't much on the digital channels I actually record (I only have a 
cable box for the HD channels), so I've never really had to wrap my noggin 
around this one... And most live TV I watch, I just use my cable boxes 
directly.
