Uh? Weird... :-?

"-sameq" just tries to use the same quality than original source :-?

Anyway, I guess mencoder can rotate the video just in one step (without 
needing "ffmpeging"), have you tried to...?

***
mencoder 1050_Lightning_talk_Redirecting_require.ogv -oac pcm -ovc lavc -lavcopts vcodec=mjpeg -vf scale=320:240,rotate=1 -o output.ogv
***
