Now we come to find out some even worse news about CableCARD and Vista: not only will you not be able to re-stream your high def media to other Windows machines (sorry, Vista capable Media Center Extenders only, i.e. the Xbox 360, and not much else), you won't even be able to transcode and sync to your PMC or other devices, as is currently possible.

ENGADGET: Vista unable to stream, convert CableCARD media
