Re: DirecTV HD DVR:It's your receiver!
What's an optical block?
I heard from my local sat guy that DN lost their latest bird shortly after it was launched and it was to be used to carry their new HD channels. So their capacity has been delayed for some time, but sooner or later they'll get it all figured out. Meanwhile, they do have some HD content, but I'm not sure they're going to be any better than DTV quality-wise. Personally, I don't even understand the difference between providers. It seems like I heard somewhere that neither one of them broadcasts in true 1080p. DN uses Nagravision to provide security and they've recently begun sending out new Nagra3 cards to all their customers. Supposedly 128 bit encryption. And they use something called 8psk or something like that while DTV uses MPEG4 compression for HD. Any one know what the difference, for practical application, between these two compression schemes is? Does one require more processing power than the other?
