Help me

Look I have an icon that someone made for me that I want to put on website. Hey Blendroid btw thanks for making it! He saved as .blend and .avi but I want to put on webpage. I want to use flash mx except when I put the .avi in flash mx it looks like three picture all playing at different stages of the video. I was wondering does anyone know how to save as a different video output? Whenever I save as like quicktime it comes out real sucky. Not even out as a video.
