Of course, you can do real-time DIVX encoding with mencoder but there is
 a noticeable loss of quality. Higher quality conversion requires a
two-pass approach which is slow even on powerful machine.

Don't think that is what Richard was saying, uncompressed streams are
mega huge and the rate is so high that you need a mega fast PCI card.
Even digital video (DV) cameras compress the data at about 5:1. MPEG-2
streams are still big, 2GB for 30 minutes recording. DIVX/XVID are much
smaller 250MB or less for 30 minutes.
