One other thing you could try is this-
If you have a generic beamshow that you
a) don't have the music for
b) don't like the music for
No problem-
Just start by finding a music file (you actually have and like) that roughly matches the duration of the show in question.
Next, just start tweaking the effects on the timeline to sync up to the new audio track, both in start position and duration. Shuffle them around and play with it.
I have tried this on a few of the sample shows that I otherwise would not have used, and the results are definitely better than just tossing the shows in the "whatever" folder.
I suppose it would depend on the security/privileges, etc of the particular show you started with, but it is usually feasible. I doubt I would do it and upload it due to the reuse of the original frames involved, etc, but if you are just doing it for fun I don't see why not. This is a much easier stepping stone for making your own show than starting completely from scratch.
Anyway, just a thought.
