When trying to read the DVD, the blue screen comes up:
"Windows - A fatal exception 0E has occurred at 0028:C18AB55 in VXD DSOUND (03) +00000B95. The current application will be terminated" etc.
The DVD player was working fine in December, before the upgrade to Second Edition.
Dell worked with me to remove and re-install DVD player and Sound drivers. No change. They suggested that there may be something wrong with the Second Edition install.
