I got a form submission recently concerning Ultrakid DVDs. This is what part of it said:
Joshua the Ultrakids movies were great. I wonder if you could copy it to DVD and sell it so everyone could buy it? It will be more exciting when you burn it to DVD.

Why don't we make DVDs and sell them? It would probably cover some of the costs of making the movies, right? (those movies actually cost something to make them, don't get me wrong)

Well the answer is simple: we can't sell them because we use copyrighted music in the movies. Some of you are probably listening to the movies and saying "Hey that sounds like Kung Fu Panda or X-Men."
If someone composed and recorded custom music for the Ultrakids movies, then we could sell them. Unfortunately, that is rendered impossible for Ultrakids 1 and 2. The reason why is that the copyrighted music is imprinted onto the audio track, mixed with the sound effects and voices. To take the music off would require serious re-editing.
On the other hand, Ultrakids 3 is off the hook because I edited it with Premiere Pro and taking the music out is a simple task.

So there you have it. The reason the Ultrakids isn't on DVD.

But do not despair. There is something new coming soon, something big...this April...

P.S. There is a hidden music file dedicated to the Ultrakids somewhere on this site...
