Video_TS files and grey screen

Question

So i have an original copy of a movie and i wanted to copy the TS files to my HD. So i grab the video ts folder and drop it in the maxtor. Now when i go to play the movie through the ts folder option w/ the dvd player i get a grey screen everytime telling me to shutdown my computer. When i put the original dvd in the tray and play it direct from the optical drive it plays fine.
I tried another experiment too, i left the movie in the tray and chose to open the movie through the ts file option from the ts files in the maxtor hd not the original movie ... still plays fine.
So now when i take the movie out of the optical tray and play the movie directly from the ts files it gives me a grey screen again
Why is this ?
Did permissions repair a couple times and no luck
any help would be great
Thanks

Answer 1

Vince, you are not able to take TS files out of a movie and play them like that.
If you are dealing with Commercial DVD Movie.
There are specific methods of copying this type of media, It takes a minimum of 2 pieces of software using a Mac.
It can be done with 1 using a PC.
The reason it will play for you is because your player is allowed to read the Encryption, and Security enhancements on commercial DVD's
So in a nutshell you have to Rip the movie, and then you can move the movie folder to your Maxtor, I doubt you can play it like that.
Here is the info you need.
