What type of DVDs are you trying to play? Are they movies or data type? When you place in a DVD movie, do you see the contents of the dvd in Windows Explorer?
Is a software DVD player installed?

I moved a Pioneer DVD-Rom 105, graphics card (ASUS V7700 ge-force) and software ASUS DVD 2000, from one computer where it was working fine to a Dell GX150 when I upgraded my computer. Both systems run win K2 prof. The DVD will now only play a CD. It will not play the DVD's that I know it played when installed on my machine. Any suggestions? SL
