Ever had flash make you reimport a .avi file after you have already imported it but

with quicktime settings its driving me crazy! I go import to stage i pick my .avi i tell it to import the whole thing it starts importing it and then when it gets done it brings this menu up that tells me to import it again as a quicktime so i import it a second time and then it just messes the whole video up.

Anybody else had this happen?
