Mencoder converting files

Ever wanted to play a file that your favourite mplayer does not want to play?
Or it shows other difficulties?

Recently I got some tech movies in .flv (flash) format.
Mplayer1.0.1rc1 plays them, but you cannot seek in those files.
Problematic could be as well .mov files.
For the .flv files you can checkout the latest version of mplayer from the subversion.
You can though convert to a format that mplayer accepts without problems (like .avi)

mencoder input.flv -oac pcm -ovc lavc -o output.avi
mencoder input.mov -oac pcm -ovc lavc -o output.avi

Happy watching....
