You're not using an aspect override (in frontend settings under 
"Playback Settings" in Myth, are you?  That will "break" some things on 
some configurations (aspect overrides are only required for users who 
don't properly configure their systems or who capture at, for example, 
4:3 but want to always stretch output to 16:9).

I completely agree with Rich's suggestion--connecting the firewire to 
the TV directly would verify whether the problem is yours or Comcast's.  
If you can't do the firewire, you could try connecting another STB 
output to the TV, although it would still be possible that the STB is 
just doing firewire output incorrectly.

If you do go down this road (and many--including Daniel, who will 
probably otherwise end up doing it himself--will be pleased with your 
contributions), please look at implementing this as Daniel requested 
(separating zoom and aspect ratio).  See, also:
