I personally use (and recommend to everyone) Synergy. It's great, and they're working on a new version specially for Tiger, but I've been using the old version for it and it's been working perfectly. I'd highly recommend it. I have command-f10 as rewind, command-f11 as pause/play and command-f12 as fast forward.
If you're looking for a better solution, definately try Synergy.
