That is correct, to the best of my knowledge -- and I'm pretty sure my knowledge is as complete as anyone's. There have been no HD broadcasts of the OT, anywhere, anytime. The best is PAL DVB (576P), with a Fox 480P airing of Empire and Jedi a close second. So what you're getting on TB or GKar is state of the art, with probably no (or minimal) re-encoding artifacts.
