Dear saraskrishna,
This CD [video+audio] on Annamalai Swami was made by David
Godman with some help from others and was sold for Rs 150/-.
I bought it through post by sending a money order co/ Sri Ramanasramam, about a year back. David insisted on money order, since he could not encash several cheques by going to bank everyday. I am not sure whether it is available now. It is an interview with several foreigners with interlocution of Sri Sundaram in English along with English subtitles. It runs for about 100 minutes.
You may send a M.O along with courier charges, say Rs 200 to his address c/o Sri Ramanasramam and try your luck.
Arunachala Siva.
