I suspect you can use your own DVR, but it would have to be one provided by dish, and the upfront cost of purchasing it probably doesn't it make it worthwhile since the prices seem to basically include a free/low cost unit without much additional cost.
The RSN on dish carry warriors/sharks/A's/Giants game. I think if a game is blacked out, it won't be shown, but not sure what the current blackout rules are. NFL games are carried on standard networks (CBS/FOX?) or ESPN/TBS I think - I don't think I've ever seen an NFL game on the RSN.
Dish does have something like a league pass which would give you every game in the league, but that costs a bit (every league seems to have its own package).
