Cob, there are so many tutorials about sony vegas on youtube, just check them out ;)
to slow down/speed up a vid simply hold ctrl and then you can squeeze it the way you want

@V: my youtube fucked up, so i can only rate a part of it. So far it seems very cool. the sync is nice and replays (of course) are awesome.
effects are set well but not too much.
so this get's a 9/10 from me.
