DVD not working since I upgraded to XP

[allegate]

OK, it started when I did a clean install of XP. After that, I couldn't watch DVD's on my computer anymore. the error message says that there is a problem with the copy-protection on the DVD Drive. I called Samsung about it, and the tech I got was VERY unhelpful, to the point of insisting I was wrong. (It says the drive has problems, I told him that, and he said it wasn't the drive. whatever.)

anyways, I'm using the XP version of DVMatics, so I know I have the latest software. The tech guy suggested a different dvd software.

So is it drivers, or software, or hardware? anyone ever seen this?

I did come across this with a quick search may or may not apply:

Gives the German manual for the application,I dont read German so it may not help.

There is mention of the inclusion of inbult security features in the software [below] so you might want to try a different player to see if its a software problem.
