I love Texas Road House
That means that they just have to make theaters nicer giving you a reason to see the movie there rather than at home.
I don't think they can really adjust the price of disks. I don't think the market will support them raising the cost of dvds to make up for lost revenue.
The only option I see would be to charge an increased PPV fee $20-30 to watch a movie at home the same day it is released in theaters.
