Not a clear title...let me explain.

I have an LG 'super multi' dvd player/burner installed on this comp. It will play many dvd's just fine but on some dvd's, I get the error oxcoocd1163 digital copyright protection.

My neighbor loaned me a couple of Western dvd's and neither will play...I get the copyright protection message.

I have the XP codec pack 2.5.0 installed...I think this is the most complete pack...could be wrong.

Also...I have Media Player Classic and also WMP...and I get the same result either way: will play dvd's just fine...but just doesn't like Westerns.. !

Now...I have tried to play this dvd on two other comps that I have...both XP machines...and this dvd will play on one of them ( also has an LG player ), but not the other ( a Lite-On ). I believe that I have the same codec packs on the other two machines...would need to check that to be sure.

So...scratching my head..
