The repo of for the frame level multithreading can be found here.
http://gitorious.org/projects/ffmpeg/repos/ffmpeg-mt. I've just tried
it and while it utilizes both cores equally with a HD PVR recording it
has problems to decode the recording correctly.

The firmware is preloaded in a NAND Flash, Windows is only required to
upgrade to a new firmware version.
