Not really, since wmv is a compressed "lossy" format anyway.
Converting to raw avi is just a way to get it to a workable format. This
format took a 32M file and turned it into 1.5G - definitely not a
"usable" size. after recompressing to xvid I noticed no difference in
quality from the original wmv files.
