For the past 3 days I been looking for just about every flashback I could find. (I even asked some people here, you know who you are) I had found about 25 minutes of footage, which is about the length of an episode. With this footage I went ahead and created "The Vegeta TV Special" which can be seen here in parts one and two...

I hope you enjoy it. I tried to edit it took look like a TV special.

Some production notes: I actually had to cut a scene in this youtube version your seeing, its right after Frezza blows up Planet Vegeta. I had to do this to keep it under 100MB. Yea the thing was huge. Your not missing anything it just establishes how ruthless Vegeta, Raditz and Nappa are to innocent people.
Another things was the name why name it the Vegeta TV Special? Well, cause it can mean so many things like Planet Vegeta, King Vegeta or just the Vegeta we know. Also, at the end there is a song (I wont say which one) and some cool ass flashback of King Vegeta turning into a giant Saiyan Ape is playing, this is actually where I was going to put credits. I did everything myself though, so it would look really tacky and lame if I put my name for everything. Then I thought maybe I should just credit Toei, Akira Toiryama and the voice actors from this movie. But then I'd have to put it in Japanese so it would actually go with the movie...so I decided not to put anything. But I kept the scene in just cause its so friggin hot.
I suppose thats pretty much it, hope you enjoy.
*Note: If the name on youtube comes up as V and V2, its only temporary.
