DivX is pretty much a staple for anyone who downloads videos from the Interwebs, as virtually all videos distributed that way are compressed and encoded using the DivX format. The DivX player has always been free of charge, but DivX Pro, which you need if you want to create your own DivX files, costs $19.99. Or not, if you hurry up and take advantage of a DivX holiday promotion offering DivX Pro absolutely free. It's available for Windows and Mac users, though I don't know for how long: the site doesn't say when the promotion ends. (If anyone does know, hit the Comments page and speak up!)
