The basic job of a CoDec (Co mpression/Dec ompression) is to read the source video, then output it (with a bit of post-processing tweaking that’s sometimes available in the codec itself). The tweaking doesn’t have the ablility to massively increase quality. In most instances, the changes are not noticeable.
In essence, for a movie to be good quality, the actual movie needs to be encoded in good quality from the very beginning. If the movie’s encoded badly, then it’ll look bad. No amount of tweaking can rectify a poor source, or poorly encoded movie.
It’s best summed up in this glossary entry at DVDRHelp.com - GIGO - (http://www.dvdrhelp.com/glossary#garbage%20in%20garbage%20out)
