[rescue] DVB vs. DBS?

Friend and I were talking about building PVRs and the feasibility of recording
digital satellite (as in Dish Network) programs instead of CATV stuff.
I did some googling tonight and I'm wondering if someone can shed some light
on the differences between DBS and DVB.
I think that DVB is the international agreement/standard towards digital
television, be it satellite, over-the-air, or cable. In the US, the
regulatory body will be the ATSC, and the US standard bears the same name.
HDTV is one of the formats specced under "DVB".
DBS, on the other hand, is "old-school" digital, as used by, e.g., Dish
Network. It is NOT a DVB-formatted broadcast.
Do I have any of this right?
Moving on to PCI cards that would support these standards, if I have the above
correct, then it would seem that a card that is DVB-capable may not be the
same as a card that is DBS-capable.
(I'm not even going to begin to discuss whatever encryption or authorization
schemes are in use, nor the way that schedule/programming information is
transmitted. I assume that's all software once you have the hardware going.)
