n00b tech questions

[SFroehlich]

I'm in the position of coming up to speed on Direc TV for some research I'm doing. As always clarity is a little hard to come by, but I bet some of you guys have answers to these questions. Consider this a newbie question - so links to answers will be fine.

1: Hughes / DirecTV DSS vs. MPEG-2 and the transition to MPEG-4/H.264

OK, so I get the fact that DirecTV started a little too quickly to be MPEG-2 compliant, but are the DirecTV "MPEG-4" broadcasts standard H.264 streams or do they retain proprietary elements?

2: DirecTV's two new satellites are using DVB-S2?

I know DirecTV has its own 8PSK modulation standard that uses a different FEC scheme (Trubo instead of LDPC?) from DVB-S2, but Wikipedia says that the new SPACEWAY satellites that they're going to use to transmit local HDTV broadcasts will be using DVB-S2? Is this right or is it the DirecTV propprietary 8PSK "standard"?

3: Listing of DirecTV Set-top Boxes?

Is there an easy place to find them listed with their specs?
