AS3 Compressors

This may not be the right community for this, but maybe someone has had this problem before with AVI videos. I'm trying to open an avi file in AS3 to do a mini-movie icon (Live Action Sailor Moon- EP 1) and it gives me an error saying the data can't be read or an unsuitable compressor can't be found. I don't know if it's the video or what, because I've never had any trouble with AVI's before. The AVI option is checked in the file associations so I was wondering if anyone had this problem and if they found a way to fix it.

Thanks!
