I have a Presario 1675 laptop with Win98. I upgraded to XP and downloaded the new driver from Mediamatics. After double-clicking the .exe file - it unpacks into a temp folder, but nothing else happens. I go into the temp folder, but none of the files will run. When I pop in a DVD, the computer will show the title and information, but will not play.... I emailed Mediamatics, but haven't heard back... Anyone??
