I downloaded a japonese animation series and some episodes are encoded with WMV9, and I couldn't open them with VirtualDub, but Dr. DivX had no problem reading then and processing.

I got the WMV9 codec and was able to open them on VirtualDub, but now Dr. DivX do a really fast process, and the video gets really fast, like fast forward.

Is there a way to solve this?
I didn't tried to uninstall the codec, yet.
