veetid - thanks for the response. It's not playing DVD's whatsoever. I have WMP10 installed. I have installed full retail versions of the following:

Power DVD 6 Deluxe
WinDVD 6 Platinum
nVidia DVD Decoder

None of these pieces of software have allowed WMP10 to play DVD's. I've uninstalled and installed every piece of DVD software along with WMP10 over the course of 4 hours today to no avail. All I would get would be a blank screen and WMP would think that the DVD in the drive was a playlist of some sort. I have a feeling its the DVD drive I am using.
