Ah, okay. No, they're the same thing. If you're truly pushing a set at 
1080p, you're running a 1920x1080, progressive-scan resolution. Now, you 
*can* run lower resolutions inside the same timings as a higher 
resolution to combat overscan issues, so I see where the confusion comes 
from, but no, I'm running straight-up 1920x1080p, which fits the display 
perfectly (the beauty of a purely digital DVI connection).

In which case, you're likely powering the set with something like a 
1366x768 progressive-scan mode (which is what the smaller HDTV in my 
bedroom takes. :)

As long as you have the horsepower and display, you can play back HDTV 
content at whatever output resolution you like. I did a demo w/a Myth 
box playing 1080i and 720p content inside a projector's native 1024x768 
resolution the other day. Myth just scales the video accordingly.
