I have several Tivo's around the house and frequently watch a show on one box from another. Foe a few weeks I cannot access my "sports room bolt" from my "master bedroom bolt" however I can see my "master bedroom bolt" from "sports room bolt". Of course it is the dreaded C501 error code that comes up, no joy from tivo support.

Are some of them TE3 and some TE4?
Known issue since March, TE3 boxes will get a C501 if you're trying to connect to a TE4 box, but TE4 boxes can stream from a TE3 just fine.
