Doh!

1080i:  1920x1080 (16:9), 1440x1080 (4:3)
 720p:  1280x720 (16:9), 960x720 (4:3)

But the thing I don't get is that 480p is 720x480 which is 3:2???
How's that work?

BTW, this has been making me wonder for awhile because I show
DVDs under mplayer with "-xy 1.5" and it scales 720x480 (3:2) to
1280x720 (16:9).

P.S.  BTW, a 1280x1024 LCD is perfect for watching DVD movies.
You get the full 1280x720 form (720p,although most are 480p VOB)
while still leaving the 304 pixels top and/or bottom for other windows.
