They should be, it was only the 6000 that they stopped I believe. The 6100 is 8PSK capable so there is no reason why they shouldn't activate it for you.
Yes, that is why I said they have no plans for MPEG4 implementaion anytime soon. Just think if they did go to MPEG4 they could maybe get away with 10 HD channels on a TP! :yikes lol
