You can do this. With touchpad pro, you can control you laptop or pc from your touch, so theoretically if you have slingplayer open, you can control it. (you can't see the video though) you can also use the SLR REcorder,save it to a file and watch it on your itouch with Orb Live. there is about a 20-30 second delay though.
