[MEncoder-users] Need some help revising old script

[Kevin dePfyffer]

I know there are a lot of experts out there based off of some of the
post I have read so figured this is the best place to get some help. I
wrote a script (ripit) that would allow a user to select which format
and quality to use while ripping a dvd without having to type the
whole thing in at the command line. If you have a few examples of what
works really well for you and and can tell me the size and time it
takes to rip would you mind sharing. I have been updating the script
and added the ability to rip a video back to dvd so I would like to
update the mencoder portion in case things have changed since its
about 2 years old.
Here are some of the options I currently have, any feedback would be
greatly appreciated and I'm happy to share the script when I'm done
(you can still find a copy on the web a few places)
thanks in advance
BTW the 3 below have worked really well for me in the past but i
havent been keeping up with mencoder and would love to speed things up
without losing quality.
