AVI Video Jogging

Are there any other programs besides quicktime that easily allow you to jog between frames of a movie?  Especially with the arrow keys.  Quicktime doesn't support enough codecs and I'd like to study some animation on a frame by frame basis.  Quicktime hates a lot of codecs.  (XVID etc) 

Any good apps that make it easy?

Depending on the codec, you cannot go backwards except to a keyframe. It's not a problem of players, but a design issue of the codec (which is desirable - further compression).

Regardless of that, what in the hell are you doing with QuickTime!? Stop using that piece of shit abort of a player, and get a good one; at this point anything is better than QuickTime. As a codec, it sucks as well, it's a piece of shit format that forces you to use piece of shit codecs. Apple always sucked at this.
