Over the weekend I was able to play with mpeg 4 page 10 video compression (sometimes called H.264). In a word -- wow. The quality is serious higher than DivX at equivalent bit rates. A two hour movie compressed to 650 MB was almost as good as the original DVD.
Prediction -- it will become the codec of choice for copies of DVDs. 650MB easily fits on a 10 cent CD-R.
