I really fear that any chance of Directv being an 'innovator', (their words, not mine), re: HDTV programming is now completely lost with this purchase. Murdoch/Fox have a reputation as being 'anti-HDTV'. As witness, see the fact that Fox stations are still only broadcasting in 480p; not true HD at all.
It seems to me that the only way for Directv to remain viable would be for it to once again deliver the best quality broadcasting available, both HD and NTSC. Unfortunately, Murdoch's minions will only want to broadcast as many channels as they can, and to hell with the quality. Once the major cable companies gear-up to offer HDTV in all of their systems; Directv/Dish are dead except in the very rural areas.
