Including audio commentaries by the Director, Producer, Cast, etc. is gradually becoming a trend among Indian DVD's nowadays. Just list the ones you have come across. I have come across:

1. Love Aaj Kal (Eros DVD) - Commentary by Imtiaz Ali and Saif Ali Khan
2. Taare Zameen Par (T Series DVD) - Commentary by Aamir Khan
3. Johnny Gaddaar (Big Home Videos) - Commentary by Sriram Raghavan and other crew members

Any others you guys know of?

Tere Bin Laden - director's commentary by Abhishek Sharma
Sajid Khan directed films - Heyy Babyy and Housefull - have director's commentary but I'm damned if I'm going to sit through that crap.
Rang De Basanti was also supposed to have had a director's commentary

I think Om Shanti Om also has commentary?

It does. Atleast the UTV DVD does. And it's my personal favourite of all the director's commentary out their so far on a hindi film DVD.

I think, Deepa Mehta had on her films, so do Mira Nair, so monsoon wedding, namesake, water!

I dont know if Chadha did on her films ki chadii lol

Lets continue seeking.

Ah I remember MF HUSSAIN on his movies, for sure Madhuri one Gaja Gamini, very lovely

- Main Hoon Na (Eros) - Commentary by Farah Khan
- Dor (Excel Home Videos) - Commentary by Nagesh Kukunoor
- Rock On (Big Home Video) - Commentary by Abhishek Kapoor, Farhan Akhtar & Jason West

I think Bluffmaster [Abhishek Bachchan] & Taare Zameen Par also had some commentary tracks.
