I have a few wmv files and I am trying to create mp4 from those using MEncoder. Initially, I am trying to decode those into avi though. The quality of such output avi appears bad. I am using simple command line such as 'mencoder -i 01.wmv -ovc lavc -oac copy -o 01.avi'. MEncoder seems to use wm*.dll codes from 'windows-essential-20071007' (part of mencoder download). The wmv file plays great in Windows Media Player 11. So, is it possible to have mencoder use newer and possibly better DirectX DMO to decode wmv?
