D* only ever had a Handful of Mpeg 2 HD they where on the 110 satellite.Since I don't keep up w/them I didn't know. So when did they finally move to MPEG 4?
I think it was HBO,Showtime,HD Net,HD Theater,TNT,Universal HD,and HD Net Movies,PPV HD, PPV Event HD.
And these were Dropped completely Earlier this year.
But they also have had a Mirrored Mpeg 4 version since I believe when D11 went live.
When They Started using Spaceway 1 and 2 then Some DMAs got Mpeg 4 Locals in HD first, back in 2006,Then D10 went live in September 2007 which was a Full MPEG4 conus satellite with also spotbeams.
So D* was doing more Mpeg 4 HD long before E* was.
Voom was Mpeg2 when I started service with E* in July of 2007. I'm not 100% sure if Voom moved to Mpeg 4 before they were Dropped.
