I'm a big advocate of at *least* two video capture paths for most  
MythTV setups.

Directly related to this, I did a full digital channel scan with my  
Comcast feed last night, and have been poking at everything MythTV  
thought might be a channel. Scanning is far better than it used to  
be, far fewer things the scan thought might be a channel that result  
in nada.

Anyhow, what I'm seeing leads me to believe that as it stands today,  
without involving a cable box, you can't get anywhere near as many  
channels off a digital cable feed as you can off the analog side of  
the same feed. So whether you're capturing the analog channel or the  
digital version spit out the cable box (at which point its been  
converted to analog), you likely still need at least one analog  
capture card if you care about recording channels like SciFi, Comedy  
Central, Cartoon Network, etc., unless you have a cable box that  
spits the digital versions out its firewire port.
