Zarak;

Your are talking about those rips, telesych and those are bad quality. If you know where to look ... hint RISCISO ... are groups that make ISO DVD copies and dump them in places. Those are actual ISO copies of the DVD which people down load from 'cough' newsgroups and rebuilt the pieces and burn into DVD. The quality is exact as originals both video and audio.

disclaimer: I do not condone any of this.
