DivX tries to one-up Adobe with its "DivX HiQ Beta 2," a whole bundle of applications. HiQ boosts web video playback quality and performance by switching to the DivX Plus Web Player on popular websites like YouTube, Vimeo, and DailyMotion, and offers an alternative Play button.
Just look for the DivX HiQ button on any of the sites, and hit that button, DivX takes over and plays the source video data using its own codec and you'll enjoy web videos with fewer interruptions, smoother playback and more vivid colors.
Here's how it looks after installing the "DivX HiQ":
In addition to DivX (.divx, .avi) and DivX Plus (.mkv) video formats, you can now publish MP4 and MOV videos using the DivX Plus Web Player 2.1 beta. The following table explains the expanded format support capabilities of the DivX Plus Web Player 2.1 beta.
