You can probably watch any of them. Just try em all, the worst that will happen is the video is skippy and it clogs up your download speeds for a short while.

:p

FWIW 720p 1280x720 is the closest to the 1440x900 native resolution of the 17".

I tend just to use Front Row...

Either 720p or 1080p. Your resolution is in between those. If I were you I would probably go with 1080p if you have a fast enough internet connection.

I would recommend 720p, you wouldn't notice much difference as the enlargement would be minor if full-screened.

NO.

It also depends on CPU and RAM

the iMac i had chugged when i played HD trailers (1080p) 19fps compared to the original 30fps its supposed to play)

720p on the other hand works fine, but doesnt look as good

uhm...the imac you had was probably a G5 right? if so, no wonder it got bogged down while playing 1080p!

mitch has an intel core duo that should play 1080p very smoothly...that along with the ati x1600 which helps decode HD videos.

Apple say it recommends a 2.0 GHz Intel Core Duo or faster, so maybe the 1.83GHz cannot keep up a steady 30fps. Although such a large framerate loss sounds a bit odd.

FWIW I believe all of the HD trailers on Apple's site are 24fps. So your iMac isn't sucking wind quite as bad as you thought it was. ;)

Isn't 24 fps standard for film? 25 fps for video in the PAL world and 30 fps for NTSC video (in both cases due to being half the frequency of the AC mains power)?

Yes.

But HD is a new beast w/a new set of rules.
