That's where DVD ReBuilder (DVD-RB) comes in. This program was built to
bridge the gap between the incredibly easy but limited "one-click"
solutions and the incredibly complex but high-quality methods of DVD
ripping and backup. Another advantage of DVD-RB when compared to older
methods is that it doesn't require access to an expensive authoring
package. DVD-RB includes its own reauthoring engine that reconstructs
the DVD in a way compatible with its original design.
Over the course of the past couple of years DVD ripping techniques have
changed dramatically. Newer "one click" programs have made backing up a
DVD a fairly simple process... but there is a significant trade-off.
The quality that can be attained by even the best of these programs is
poor in comparison to original techniques that used Cinemacraft
Encoder, TMPGEnc, or other top-notch encoders. The reason is simple.
When using one of these encoders the picture is rebuilt from scratch
and optimized for the resulting bit rate. One-touch transcoders usually
change quantization and/or motion info in order to lower the bit rate.
This can result in pixelation and poor overall picture.
