Not sure this is the correct section for your post, but anyway...
I also enjoy Bollywood movies, but it's quite difficult to look for original Bollywood DVDs locally. I remember seeing some titles at an Indian restaurant/mini-mart near UN Avenue, but this was quite some time ago.
The original DVDs of Lagaan: Once Upon A Time in India & Saawariya were released commercially in local video stores, but I think they are hard to find now (I do have them & both are quite good movies). Mira Nair's The Namesake DVD is still available in stores, but I think this is more of a USA production than a purely Indian one.
I have also seen Ra.One. It's good fun in parts; corny in others.
