[MPlayer-users] Advanding to next keyframe

[Ergzay]

If you fast forward using a left or right arrow key you jump to the 
closest keyframe at 10 seconds from the current position (or atleast 
thats my understanding of it). Is there some way to jump to just the 
next keyframe? I do Quality Checking for an anime fansub group and I 
often find myself rewinding and re-watching a section over and over and 
I would like to fast forward or rewind by a smaller increment than 10. 
Is there some way to do this?
