I have some old movie files lyimng around in the now defunct VIVO format. Apparently there is some mecoder library for this codec, but ffmpex doesn't seem to support it. When trying to convert one of these files, I get the message:

The above seems to imply that vivo conversion is possible in principle, but I am not wizard enough to get mencoder to do this via command line. Is there any chance for this in a future version of ffmpegX?

Many thanks,
