I've been ripping DVDs for quite sometime now. I use robot4rip to rip the data and GordianKnot to compress it, with DivX 5.1 Pro. I've been getting pretty decent results and have gotten quite good at it, but I keep getting this nasty feeling that maybe I'm missing out on something by not trying out XviD or Nero's Recode. Can anyone help me here? Is there a codec better than DivX 5.1?
