I've come across some strange behavior when playblasting motion jpeg .mov's from maya, namely that when I specify HD resolution, and then inspect it with ffprobe, ffprobe indicates that it's actually not HD but 1920 x 1088, with a display aspect ratio of 30:17....what gives?  Anyone come across this before that knows why this is happening?  I should note that I inspected the resolution with both ffprobe and mplayer, yet in the rv media player it shows as a correct HD resolution.

Any insight is welcome...

Apparently 1920x1088 is considered full HD by a lot of software. Google shows several forum posts about it in various A/V forums. Also, apparently a lot of software ignores the 1088 and reports it as 1080, just to make it more confusing for the likes of us!

Adding a crop flag to ffmpeg seems to have solved this:
ffmpeg -i INPUT.mov -r 24 -s 1920x1080 -vcodec CODEC -vf crop=1920:1080:0:0 OUTPUT.mov
