Here is one that is really simple to use. You can use it to play your videos in slow motion. http://www.yessoft.com/software/sportvideoplayer/sportvideoplayer-2.zip (if this is already posted , dont panic. There are lot of people who doesnt bother doing a search. This might help them) You can review frames (by using left and right arrow keys) and advance and forward at a frame level. Very useful.
