You need to do a channel scan for digital channels on any scannable 
input (i.e. pretty much everything except analog capture, firewire, and 
CableCARD devices).  You can't just create channels with the channel 
editor to test.  Did you do a scan with mythtv-setup?

Once you get a good channel, it should do the proper aspect ratio 
(assuming you've configured X properly).
