So, it appears that Sigma Designs has released a video compression program that consists substantially of code stolen from The XviD Project. Links:

Discussion forum thread with a number of XviD developers participating
XviD is a free MPEG4-based video codec, distributed under the terms of the Gnu Public License. This means that anyone can modify the program and release it, but if they do, they must not remove the GPL notices and license text, and must include the source code. Sigma Designs released a product that includes portions of the XviD Project’s MPEG4 Encoder, and claimed it was developed by them, keeping the source code secret. When this story broke, they quickly released the source code, but still claimed it was their original software, and are only distributing it under a license that violates the GPL.
These bastards are ripping off a community effort for their own financial gain, stealing the hard work of the people that created the XviD software. I don’t have any personal stake in this, but I’ve been using XviD, and have been following its development closely. It is a very cool project (or was, as development has stopped until this issue is resolved), one I hoped would succeed. In closing, Fuck You Sigma Designs. I hope the XviD Project gets some financial backing and sues you out of business.
