7/28 On2 Technologies, maker of the VPx series of codecs who had previously released VP3 as open source (now to become Ogg Theora), have released the VP3 successor, appropriately named VP4, as free product to the end user. However, VP4 did not perform too well when it underwent my testing regime a while back, and VP4's successors VP5 and VP6 are already out (and not available to end users nor any independent journalists doing codec comparisons).
