Cool,
First we need to understand that Ppl got used to a habit of watching New or fresh films in Home with pirated version(It could be taken from Theater on mobile cam, hand cam.. or even imported from foreign countries like Singapore or malaysia.
So none of the activity can bring the crowd back to theater at all for any time in future, the are ment to be "TV audience or fans" .
At same time the pirated version also cannot be stopped or blocked or even limited as "Its something happening like a Underworld business including the Cops

"
The ticket cost has been raise heavily, even that is some how acceptable but the GREEDY multiplex owners\management restricting even a water bottle to be carried inside the Theater hall, and selling the 12-16INR bottle for 25 and all the eatables are double then available outside.
So the film viewing cost includes Film ticket+ Misc and Misc are bit more than than the ticket cost.This is one of the reason none is turning out to theaters as getting scared.
Satellite rights is one of the best way get a good profit for producer before the release of film.So SET top box rights screening also gives a new revenue for Producer of the film.
If you have read recent interview of Ulaga naagan then, then might have come to a conclusion.
As per the Stat only 3% of the TN people\Fans have DTH connection for that particular service provider.So i dont think how this going to affect the Audience coming to theater?
Moreover the film cannot be Reproduced,so spreading of duplicate Copies is not possible.
In Conclusion " If a person have Mind set- to watch in theater, he seldome think to watch in Home in Pirate version"
If someone has mentality to watch film in home"feeling its cost efficient" then no way we can pull them to theaters"
If the theaters reduce the ticket Rates and snacks rate,Parking Rate, then Pirate dvd can be stopped also protesting against DTH release also will be meaningful.
But we all know nothing going to happen.
Lets see how the Future of Tamil films is going to be!
