Adding music to a video clip?

[OTB_again]

Technologically challenged here...I recently shot a sweet 4min .avi clip going down 5 Oaks from my helmet cam...but how can I go about adding music to it?

I tried to do it using Windows Moviemaker and importing the desired tune from iTunes but I got a missing codec message. That's where I got bogged down...trying to figure out which codec I need, etc. Or am I going about this all wrong?

yeah, if you try and use i tunes music it wont let you. if you burn your own music from a cd then you can just pretty much drag it into movie maker. theres probably a way to use i tune music but its just easier to just get it from a cd. unless of course the cd music is encrypted or something like that. btw while editing your film save, save, save. especially with windows movie maker. if the music is encrypted itll just boot you completely out of the movie your making and sometimes it wont save.

If possible, purchase (or otherwise obtain) the music as a WMA file. If it comes as a M4A file, it likely won't work, but WMA files should work fine.
