That is not unrealistic at all to ask.
There are much applications with easy to understand tools and settings
to control deep inside very complicated processes for the "engine" behind.
At least it should be normal within the help manual how to use these
controls, but for the previous YASA application not one word about it.
It is like using MSDOS commands within (or against) a Windows user
interface.

I think you don't understand the problem itself.
The images from the DVD is not the problem, they do not contain the
blocky artifacts. It is the output after ripping the DVD to another
format and size that do contain blocky artifacts only at the point of
very fast changing movie "scenes".
Typically at more "slowly" changing movie scenes (the most of it) the
problem is not there at all. Tools as "Deblocking" should be help to
avoid these problems in fast changing movie scenes only.
It should be possibly as the basic material is without errors.
For the sake of quality images for compressed output maybe less
compression only at those fast changing scenes. A smart application
should look "forward" to detect these fast changing scenes and change
the policy for converting. So a complete movie is converted and
compressed in the most efficient way for a general even quality within
the possibilities of a given general compression setting.

I hoped power users in these newsgroup could help with their experience,
but seems the only one that are posting to a question don't have
experience either like me.
