 * Usage:

Ok boys and girls, here it is, the
first DVD CSS resampler.  What it
does it take any DVD stream, and use
PowerDVD (v1.6 or possibly 1.5 & 1.3)
and resamples it to an AVI code.

You can convert directly to MPEG 1,2 if
you have DVMPEG installed.

You can also convert to MJPEG for video
editing using one of the publicly available
MJPEG AVI codecs.


Ok, here is how it works:

First, load PowerDVD v1.6 (version 1.3 or
higher may also work, untested).

Load up any DVD movie, seek to the start
of the movie and press the [Pause] button.

* Tip: You can pause then move the track back
       and it will remain paused.

Load up Power Ripper select how many frames
to capture (DVD movies are 24fps, so each
24 frames means 1 second).

There are 2 ratio modes,

1. Half resolution
2. Quarter resolution

There is also a custom mode that will allow
you to select any resolution.  However, the
quality won't be as good since the math is
simply always better when dealing with
fixed sizes.

There are some issues when using ratio
scaling, the MPEG format doesn't like image
widths that aren't dividable by 16.

The AVI field allows you yo select a file name
for the generated AVI file, do not use the
".AVI" extension, it is included automatically.

The AVI will be created in the PowerDVD screen
capture directory, make sure it's defined correctly
or the program won't at all.





 * Speed:
----------
After starting the conversion process,
make sure to switch over to PowerDVD,
having the PowerDVD user interface
as the active application improves
the conversion speed by quite a bit.

I got around 180 frames per minute
on my P2/300mhz using MJPEG encoding
at maximum quality (which looks great
btw, but is rather big).

That's around 8 times slower than
real-time conversion.

Im don't think speed can be improved
by much, basically, a faster CPU will
get more done.
