While Tom's reviews of MPEG-4 encoding do give us a good sense of which processor is fastest, the one missing link that I see is an IVTC step. Everyone I know who does DIVX encoding from an interlaced source uses an IVTC (interse telecine) step, rather than using flask (or another program)'s interlacing smoothing options.
You end up with a noticably smaller file size, and (IMO) a better looking product. While the relative difference between a P4 2K and an Athlon XP 2K+ is useful, the actual hard numbers are useless from the point of most of the hardcore DIVX encoders I know.
Frobnoid is absolutely correct. You hardly ever need deinterlacing done in any other way than though IVTC. I also had a major gripe with the "Higher Quality with Flask 4.1..." guide due to quick assumptions like "DivX3 is still better than DivX4" without any sort of information to back this up. With some tweaking (i.e.: Spending 5 minutes on a search engine to read up on it) the DivX4 codec can arguably produce much, much better video than DivX3, and be less, um, illegal. Since when are THG guides based on opinions rather than facts?
