Good to hear that this has reached DVD. I have caught it a few times on one of the BET stations -- once even from the beginning!
(Each time purely by accident because I zone out on detailed searching of TV listings lately.) I live in one of NYC's Boroughs, so we have a few of their stations, and I haven't a clue which one I hit to find this, or whether it might even have been Black Starz.
However for anyone who hasn't seen it and can't get their hands on the DVD, it would be worth a detailed search. The documentary seems well done and well researched. That's why i stopped to watch it actually, only later tumbling to the fact that this was Ms. Isles "Scandalize My Name".
As to the new documentary on the Healing Gardens of NY -- after taping the initial broadcast, I have stumbled over it a couple times on the bounce. They're now in the midst of a begathon, so no telling whether that will increase or decrease the odds of it being rerun again soon.
