PX-708A problem

Hello everyone!

It’s been a while that I’m having problem with my Plextor hardware DVD writer or it could be the software , don’t know wich one, but I hope someone help’s me in finding a solution.

I got WindowXP, a P-4 computer.
So my problem is the DVD reader cannot read any normal film DVD!
It use to do well, before my actual problem.

It work fine with the recordable DVD, I save data on it!
But again trying to read a film on DVD it does’nt read it at all.

Someone told me to erase DVD X-Copy gold, version 2002!
And to erase XP service pack 2.

Anyway, thanks for any kind of help!
