Thanks Roman but it gives this error:

If you wish to use libavformat muxing, you must ensure that your video stream does not contain B frames (out of order decoding) and specify: -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames on the command line. REMEMBER: MEncoder's libavformat muxing is presently broken and will generate INCORRECT files in the presence of B frames. Moreover, due to bugs MPlayer will play these INCORRECT files as if nothing were wrong!
Cannot initialize muxer. Exiting...
ah, ok... i see. you use a different (older) version than me. try to do what the error message is telling you: add 'i_certify_that_my_video_stream_does_not_use_b_frames' to your -lavfopts.
this would look like this (all in one line):
mencoder Skim.wmv -nosound -ovc lavc -lavcopts vcodec=mjpeg -of lavf -lavfopts format=mov:i_certify_that_my_video_stream_does_not_use_b_frames -o outfile.mov
someone mentioned, that vlc provides also encoding possibilities. if mencoder is not working or too hard to deal with, try vlc.
cheers roman
