how to encode the movie

[yasi]

hi to all
i have a store to sell series and movies.
my translators try a lot to translate the subtitles of bought series and movies to our hometown language .
Then we make the series hardsubbed to sell.
the problem is that some reseller buy them and sell them without any trouble
i want to write a program that it encode the files so that
they could not be playable .
i had written a program that needs a code to run the main player for watching the series.
each buyer should receive a code from my site to watch the series,
till this part there is no problem
the main problem is that the episodes can be watched by any other program such as windows media palyer,jet audio,km player,meaning my program to watch the episodes is useless.
please tell me how to encode the episodes so that they can't be watched by any other program
thanx alot

Let me get this straight. You buy copyrighted TV shows and movies, add subtitles in Farsi, copy them, and then illegally resell them? Is that about right? And then you object when someone else takes advantage of your hard work to copy your videos and resell them himself? I'm sorry, but I just don't have much sympathy for you. But to answer your question, I know of no way to prevent anyone from copying "your" stuff.
