I was watching Prison Break last night (and last week for that matter), and DVBViewer was displaying something like 720 x 574 at the bottom of the window when not in full screen mode.

Does this suggest that I was not watching a HD feed of the program?  I've seen other on this side mention resolutions of feeds.  Where do you get this information from in DVBViewer?

I've got the PowerDVD H.264 codec running and believe I've set up DVBViewer correctly.  And the picture does look HD on my 1366x768 Bravia.

Anything to worry about?
