I tried that.  I added a local digital cable service to my Zap2it account.  
I can't even watch Live TV with that setup--I get no picture from tuned 
channels, and after leaving live TV mode and trying to come back, it tells 
me it's busy recording on all inputs (which is false).  The problem with 
that idea in general is that I can't actually scan and add any channels for 
the digital cable service that I don't have.  I have to leave mythtv-setup 
without giving my DVB input any channels, and that might be part of the 
problems I experienced.

I'd just settle for that.  Anyway, even when you set your card as a DVB 
card, the Television inputs have "V4L" in front of them--the input quality 
should be about the same.  The other day I bit the bullet and bought a 
Hauppage WinTV PVR-150, and instantly everything worked (although now I'm 
spending hours trying to fix the low volume/poor sound quality problem I 
have, oh and the card itself is extra wide and I had to pry my form factor 
case open so the circuit board didn't make contact with it).  Scheduling 
recordings works, live TV works, and there's no encoding being done by the 
CPU.  My conclusion is that the pcHDTV-5500 is simply a bad buy if you're 
planning on only using its analog capabilities for any amount of time.
