This was a simple bug about encode2mpeg checking for mjpegtools when it
should not have done it. To be fixed in the next release.

Two pass encoding is broken in mplayer 1.0pre8. You should:
use 1 pass encoding, or patch mplayer (see the README) or
use a recent SVN snapshot of mplayer.

But I'm sure "mplayer input.mpg -aid 128" will not :-).

I think you were using -aid 128 with the encode2mpeg command line but
the audio stream present in input.mpg does not have aid 128 but 0.

Please run this time:
mplayer -msglevel identify=6 -vo md5sum:outfile=/dev/null -ao null -nocache -frames 0 input.mpg

and post the output. Just to be sure.

So, if you omit -aid 128 or use -aid 0 (or whatever audio stream id
is present in input.mpg) and use 1 pass encoding it should work.
