Hmm, that's strange, there should be plenty of video control. You should be able to click anywhere in the timeline and go directly there.

Maybe there's something wrong with your browser settings, or the flash plugin? There is even an AB loop function, where you can pick a certain part of a video (like a 4 second lick) and it will loop just that over and over again.

Let us know if you're still having problems.
