I don’t think there are any straight video rental places left in the greater Boston area. The last one I knew was in Marblehead, and that went belly-up a couple of years ago. You can still rent DVDs from the “Redboxes” at supermarkets and convenience stores, but I think you’re talking about non-automated sitres.
(Heck, it’s hard enough finding places that still sell DVDs. Newbury comics used to have awesome collections, but they no longer sell them. FYE had a decent collection, but they’re gone from the area. A few places like Best Buy and some Barnes and Noble stores still sell them, and Target sells relatively new or popular DVDs… And you can get a few at used record stores and some comic shops, and I still know of a few other places that sell them. But they’re hard to come by, especially any selling older or more obscure titles. It’s much easier to buy DVDs over the internet.)
as for rentals, there are a few niche stores. There’s a Kung Fu video rental in Boston, there was a place in Jamaica Plain, and I’ve seen stores renting Spanish-language DVDs or Russian DVDs or Chinese or other languages.
Heck, even all the adult DVD places seem to be gone.
You know where you can still borrow DVDs? Most of the local libraries still have small collections. And still sell old used ones.
