Well I sure do see and hear a lot about copied movies. I have got a hold of 2 of them. It is really easy to tell. Here are a few things you can tell.

1. The  movie has a wierd looking cover over the dvd or cd. Like it was waterd or something.

2. Or it lookes like someone stretched it out.

3. It doese not come in a proper sleeve. Like just a white one from walmart.

4. Look at the disk in the light on the back where the movie is it lookes like a blue color or green.

That is a few things how you can tell if they are copied. Just make sure you look.
