Hello, I have a Dell Dimensiion 9150 running Windows XP. I have both a DVD RW and a CD RW. I can read some DVD's & CD's but not others on both devices. Very rarely it even manages to read the DVD/CD's that it previously cant read.
I have purchased DVD movies from shops which it can read and I have burned some DVD's/CD's with Nero which it cant read.
I'm not sure if the problem might be with the burning procedure.
I also have al Dell laptop with Vista and find that it can read all DVD's/CD's that cant be read on my desktop.
