Video compression.
User, not developer, question.

I backup my movie dvds. I use taiyo yuden dvd-tx8 4.5 media.
I use the latest dvdfab to hard drive, 1x1, and & nero6 to burn.
I?ve asked nero about compression algorithms but they ignore me.

Nero is analyzing the data stream and compressing it to the requested size. I expect someone else is supplying the algorithms / technology.

I?m happy using nero 6 to burn but if there is better software I?d appreciate a note.
