I have a new Dell DVD R-RW driver installed in my Dimension 3000, XP. It reads and writes to CD's, plays music CD's, but will not play video DVD's.
When video DVD disc is installed, seems to load up OK, but at last moment, "Windows media player" screen pop's up with the following message:
"Cannot play this DVD, there is a problem with digital copy protection between DVD drive, decoder, and video card, try updated driver for video card."
NOTE - I have the latest video card driver installed in my system. Plus, I have the latest Window updates for XP.
