Ok. I have gotten some MP3 visualizations (without audio) as AVIs

I need a program which will allow me to insert (and syncronize) the MP3s

Problem is: I am using EVE (Easy Video Editor) and when I add the MP3 to the AVI it becomes choppy

Are there any settings our changes I can make or am I just screwed?
(You probally don't even need to be familar with EVE to answer this)

Are there any other good programs? (I want to stay away from WAVs)
