Most probably because you failed to set the MIME type for movies. To do this
properly, add to your "Scan Rules" settings:

+*.mov +*.mpg +*.mpeg +*.avi +*.rm +*.qt +*.wmv

and add to your "MIME types":

mov <-> application/x-mov
mpg <-> application/octet-stream
mpeg <-> application/octet-stream
avi <-> application/octet-stream
rm <-> application/octet-stream
qt <-> application/octet-stream
wmv <-> application/octet-stream
