:hap2: the codec is free, divx pro(6-month trial).
Today, we're excited to announce that the DivX 6.1 codec is finally here! It sports a ton of new features and enhancements, perhaps the most impressive being a massive improvement in encoding speed. According to our benchmarks, even a modest single CPU will run anywhere from 14 to 80% faster than the 6.0 codec depending on the quality mode selected. At the same time, brand new support for HT, SMP, Dual Core, and Dual Core + HT CPUs allows for gains of up to 300%!
