I was lucky..sort of. The first time I was videotaped I looked great but that was also part of my problem. I was the type of player that was so focused on looking good that it forced me to be kind of..well..mental to say the least. I had a hard time getting down and dirty when I was younger and just couldn't scrape out a tough match if my "pretty" strokes weren't up to par. That being said, seeing yourself on video should be used as a motivator. Use it to help clean up your footwork and strokes if possible and don't let it get you down. Just work at it a bit more.
You said one magic word. Footwork. That was the ugliest part. I realized that I am so focussed on getting there and hitting the ball that I do not care how. It looked like it could be so much easier.
I mustered the courage to watch it again and I can now break it down.
The good part:
1. Serve: It has always been decent and I was happy that the motion looked pretty good too.
2. Backhand: Although my backhand is weaker, it is prettier to watch. When I played casually, I avoided hitting backhand so my first two lessons (this *was* a freelancer) I learnt to hit a one handed BH. Lack of bad habits helped here.
The bad part:
1. Footwork: I could see how my shoe soles wear out within four months. I need to learn to easily move towards the ball and back.
2. Racquet position: I could not believe that sometimes I run/move with racquet head pointing down. It looks very ugly.
3. Body weight transfer: No wonder majority of my shots lack the pop I wish they had.
4. Running forehand hitting position: This was hilarious. One of my legs would launch in the air every single time when I hit this. I had to laugh at this one.
5. Shape: Spare tire coming out. This is the first thing I need to work on. I absolutely hate that.

I do plan to tell my pro what I want to improve on now that I have a fairly good idea. I hope he does that otherwise I will buy a ball machine and put an MP3 in my iPod that keeps on saying "Turn your shoulders, bend your knees, that's a home run, good shot, ha ha ha (after he gets me with his exquisite drop shot), watch the ball, let's pick them up."
And btw the only reason I finally got myself videotaped was because we bought this cool, simplistic, cheap and a very small form factor video camera. I don't want to sound like a salesman but anyone wanting to do this should take a look at google search results for "Flip Video".
