Yeah, but first RENAME THE ORIGINAL! Call it "video_conversion.php.BAK" or something like that just in case any changes you make don't work out or if things change in the future, you will still be able to use it simply by putting back the original name.

Here's what I have been using

Code:
<?php

$cmd_ffmpeg = "$config[ffmpeg] -i '$video_src' -acodec mp3 -ar 22050 -ab 32 -f flv $video_flv";
$cmd_mencoder = "$config[mencoder] '$video_src' -o $video_flv -of lavf -oac mp3lame -lameopts abr:br=56 -ovc lavc -lavcopts vcodec=flv:vbitrate=768:mbd=2:mv0:trell:v4mv:cbp:last_pred=3 -srate 22050 -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames";

$cmd_all = $cmd_mencoder;


$convert_3gp = $cmd_all;
$convert_mp4 = $cmd_all;
$convert_mov = $cmd_all;
$convert_asf = $cmd_all;
$convert_mpg = $cmd_all;
$convert_avi = $cmd_all;
$convert_mpeg = $cmd_all;
$convert_wmv = $cmd_all;
$convert_rm = $cmd_all;
$convert_dat = $cmd_all;
I sent you the actual file in email. Let me know if it works for you or not.

As far as the new video_conversion.php goes, I'm suspecting I need to UNCOMMENT the lines in the newer version of video_conversion.php for the OLDER mcoder and comment out the new code. I'll play around with that later.
