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?

Go back to crying all the fucking time about how nothing supports the formats you use, so you can one day realise that "openness" is a shitty and useless selection criteria for these formats.
