Thanks for suggestion, I cleaned the drive and checked to see what it was.  It is a Phillips CDRW/DVD SCB5265.  I wonder if it only reads a certain format of DVDs.  Since the drive indicator in the folder for Poser 7 shows it as a CD it may be that that is the problem.  The drive does read some DVDs but I really don't use it that much for DVDs.  I did send an email to E-frontier support.  I wonder how they will fix this.  Maybe I will have to download it.  Buying a new drive is not an option.  Oh well, more waiting while everyone else wows and woos.
