Have a look at
http://www.youtube.com/watch?v=m-966jH1__8 which has a good explaination about how to get the pop you are looking for to get to the other wake. Watching your video you are absorbing the wake rather than holding the edge up and over it.
Also, to me it looks like your riding position is off contributing to the uncomfortable feeling. I'd say your hips are a little behind and out from where they should be. As they say, hip to the handle not the handle to the hip. See

You can also find these by searching "wakeboarding instructions Matt Crowhurst" at youtube.com.
I found it helpful to start standing beside the wake, take a short swing out and come back in on edge and standing firm against the wake. As you get it down, increase the distance you swing out but only as much as you are still willing to correctly launch off the wake.
There is a good instructional video called "The Book". I highly recommend it as takes you from the basics to advance, had good advise on practice drills. You can load on your iPod and review while you are on the boat.
