#16 ERROR? IN COMMAND LINE OF MENCODER

[Grant Nicholas]

THIS IS TO ALL THE DEVELOPERS OF MPLAYER&MENCODER FOR OSX

10/10 FOR YOUR EFFORTS IN DEVELOPING MPLAYER & MENCODER
APPS - THEY ARE EXTREMELY USEFUL APPLICATIONS GREAT JOB GUYS.

MY QUESTION IS THIS:

I RECENTLY HAVE DOWNLOADED THE LATEST VERSION OF MENCODER
- FOLLOWED ALL THE INSTRUCTIONS IN THE HELP GUIDE AND
ENCOUNTERED A PROBLEM UPON STARTING THE CONVERSION:

AltiVec found
Reading /Users/grantnicholas/.mplayer/codecs.conf: can't open '/
Users/grantnicholas/.mplayer/codecs.conf': No such file or directory
Reading /usr/local/etc/mplayer/codecs.conf: can't open '/usr/local/
etc/mplayer/codecs.conf': No such file or directory
Using built-in default codecs.conf
File not found: 'frameno.avi'
Reading config file /Users/grantnicholas/.mplayer/mencoder: No
such file or directory
Option vop: fiters doesn't exist
Exiting... (error parsing cmdline)

I THEN HIT THE UP ARROW ON THE KEYBOARD TO VIEW THE
COMMAND LINE WHICH LOOKS LIKE THIS:

-vop fiters,scale -zoom -xy 640 -ovc lavc -lavcopts
vcodec=mpeg4:vbitrate=800:vhq:vqmin=2:vqmax=10:keyint=240

I THEN MADE THE FOLLOWING AMENDMENT TO THE COMMAND LINE
AND MENCODER STARTED PROCESSING THE FILE:

-vop scale -zoom -xy 640 -ovc lavc -lavcopts
vcodec=mpeg4:vbitrate=800:vhq:vqmin=2:vqmax=10:keyint=240

Is there a bug in the command line???
