The most part of a DVD is being
used for compressed streams
of Video. Compared to the VideoCD
the DVD has a lot higher
resolution and higher picture
quality. But this better
quality comes with a price.
And this price is called : bitrate.
So to get the contents of a
DVD onto normal CDs we have
to achieve it that the high
bitrate video-streams gets a
lot smaller than it was
on the DVD. First DVD conversions
were done by converting the
DVD to VideoCD or SuperVideoCD
(slightly higher resolution
than VCD) but these formats
in no way came close to the
quality of DVD.
But Microsoft helped out. They
already release an MPEG4
Compressor some years ago but
no one used it. MPEG4 was originally
designed for low-bitrate applications
and for usage with low resolution
images (for example in cell-phone
or for IP-telephony).
But it is also extremely brilliant
when using it with high resolution
imagery, like, say.. a DVD.
Right now MPEG4v3 is the best
compression to be used for converting
DVDs. Here I'm presenting three
conversion methods. (you

[FlaskMPEG]
High Quality but slow (avg.
11 fps @ Athlon 500)
[MPEG2AVI]
High Quality but fast (avg.
12 fps @ Athlon 500)
[DirectShow]
