I recently joined Seventymm - the offer was a 3 month subscription for Rs 499, one movie everyday except Sundays. Its been over 15 days, but I cant get the one movie a day, as promised. These people are cheats. They deliberately delay your delivery so that you get fewer movies than you should actually be getting. Calling Customer Care is a waste of money and time - they will give you all the possible solutions but none will ever be implemented.
Another issue - they will have movies only which have been officially released on DVD or for those which they have permission from the producers of that movie. For instance, Inception DVD was officially released over 45 days ago, but Seventymm still doesnt have the DVD.
In short, all I can say is - dont waste your money on Seventymm. It is far better to download your movies from the internet, even if you are finicky about the exact DVD quality - youll easily find it on the internet, and sometimes youll find even the High-Definition versions.
