Haven't tried it, but the changelog states multi-Bframes and MPEG quantization (where have we seen that before??)

No longer uses adware in its Pro version, but there is still something fishy about it (free use of the Pro version for 6 months).

Early posts on Doom9 state that it still isn't quite as good as Xvid 1.0.1

Read more here and a quick comparo with Xvid and VP6 here.
