What is some good Avi editing software?

I have video edit magic, and it just seeems to inconvient to do anything with it; every time you want to add a song to the audio track, it puts it at the end of the file, so you have to manually scroll it back to teh beginning of the track. Thanks in advsce.

I am looking for something that you could use to easily make a music video from a movie.

Virtualdub and AviSynth.
