bugreports go to mplayer-users at .... it's a rule created by the mplayer
developers....

it has nothing to do with your processor speed... it's that a
non-interlaced avi contains first the video part then the audio ( or
vice versa), so when playing back first you read a bit from beginning of
the file, then from middle of the file, then from beginning of the file,
then from middle of the file etc....

and seeking on a cd/dvd rom is never fast compared to seeking on a
hardix.

actually why are you using non-interlaced files? can't you convert them
to interlaced?
as far as i know a simple 'mencoder -oac copy -ovc copy in.avi -o
out.avi' will solve your problems...
