I am using too pass encoding, but:
* with lavc it doesn't improve quality as much as they promised
* while using this option:
-xvidencopts pass=1:bitrate=922:vhq=4:me_quality=6:trellis
i get bitrate like 4000 and higher. I have to remove some date from
hardisk to save it ;-(
* How to use negative bitrate? If I want to fit whole DVD on one CD,
should I use -1*702*1024 bitrate?
