Without meaning to gatecrash this thread, but I have Sky+ HD (with an HD TV linked up to it), and my Sky box still displays a message advising that the HD format is not supported. It has done this with regular programmes, Anytime viewing and on occasions, programmes recorded onto the hard drive.
Sky's technicians are unable to troubleshoot, merely passing it off as a glitch in the system. Which, of course, doesn't help when you have to keep pushing "back up" to remove the error message on screen. Has anyone else come across this yet?
It would seem that, a la Microsoft with Windows, Sky occasionally enjoy pushing out their latest front-running technology before ensuring that everything is ironed out.
Oh, and they refused point blank to remove our old Sky+ box.
