what do you mean?

REMEMBER: MEncoder's libavformat muxing is presently broken and will generatewow, you are using a very old mencoder installations.
yes and no, it is indeed a very old version of mencoder, but still the most recent one, that is available as a binary. you also find _very_ old binaries in many distros.
actually, it is not more than a few weeks, probably months ago, since -lavfopts was fixed and the option 'i_certify...' disappeared, so this is not a sign, that a _very_ old version is used here.
however, compiling mplayer from svn-sources is highly recommended, because bugs usually get fixed quite quickly and more recent version can be considered to be even more stable than old ones.
yves has just recently posted the commandline to use such an old mencoder. search the list archives for "i_certify_that_my_video_stream_does_not_use_b_frames"
or update your ffmpeg installation (which version of ubuntu do you use?)
