Commercials in Bollywood DVDs

I watch a lot of Hindi movies on DVDs and I am forced to see the commercials, trailors etc before I can watch the movie. These companies include Eros Entertainment, DEI, WEG, SPARK among others. Most of the DVDs have been programmed so that its not even possible to use the next or fast-forward button. As a consumer who has paid full-price for the DVD, it should be against the law to force us to watch these commercials. If you look at some of the channels on cable like HBO and Showtime, they do not show any commercials. Even the Hollywood DVDs only force us to see the FBI warning.

Does anyone out there know if there are specific laws against forcing us to watch these ads?
