Nope. I spent a few days in summer trying to get VLC to work. I finally
managed to get totem-xine to work.

I'm beginning to see the light: so I tried -of lavf, even though the webpage
says "Unfortunately, as MEncoder was not designed from the beginning to
support container formats other than AVI, your should really be paranoid
about the resulting file."

I guess the website knows its stuff! The command
mencoder 'mf://fitImage*.jpg' -mf type=jpg:fps=2 -ovc lavc -lavcopts
vcodec=rv10 -of lavf -o gaussMovie.rm

produces a movie that realplayer recognizes as some kind of media, but not
video, perhaps, because it doesn't even open up a display.

At best is right. It doesn't make anything. FATAL is what it makes. :))
