I think he meant other than the main HBO E and W :lol:
There was an interview with Bob Ziiter of HBO on Multichannel News on 06/23/08 which states that HBO announced aggressive plans last summer to offer all its 26 multiplexed premium networks in high definition. The interview also states the channels are in MPEG-4 (which is not a problem for DirecTV, obviously).
MCN: Can you update us on how HBO's high-def offerings have developed.
BOB ZITTER: ... The last piece is that we began in 2007 to take all of our multiplex feeds of HBO and Cinemax and make them available in high-def. We are finishing that up now and by the end of this month we will have 26 HD networks, which is all we offer.
And of course, there is the DirecTV press release from June 2007:
DIRECTV to Offer 11 HBO/Cinemax Channels in HD
HBO, HBO Signature, HBO Family, HBO Latino and Cinemax Channels Among HD feeds to Launch Beginning in September of this Year
EL SEGUNDO, Calif.--June 13, 2007--Continuing to pack its lineup with premium-quality HD channels for launch this fall, DIRECTV will begin to roll out the HD feeds of 11 HBO and Cinemax channels nationally in September.
