Are there any DVDs that have the original network promos?

I don't think that there are any that have original network promos; however, there are some television disc releases that have promos in another form, like "Hawaii Five-O" for instance. From S2 through S4, each release has had promos for the next week's episode. These promos are, oddly enough, attached to the beginnings of the episodes that they promote. Each one has Jack Lord narrating what the episode will be about, with some scenes from the episode. These promos have another thing in common; Jack said at the end of them (and this is well remembered by "Five-O" fans)-- "Be here. Aloha." For some reason, #1 did not have these promos. Also, not every episode in these releases had a promo included for it, and two-parters certainly did not have them. However, that does not take away from the fact that these promos certainly drove the episodes home for "Five-O" fans.

Mary Tyler Moore season 1 has a few original CBS promos, not of the individual episodes, but promos for the show itself featuring Mary for the CBS 1970 campaign "We've Got It All Together."

The new 10th Anniversary Edition of SportsNight has the original network promos.

The Sarah Jane Adventures, Torchwood, and Dr. Who sets all come with the original BBC promos.
