I have a New Dell 4600C with a 24X CD-RW/DVD Combination Drive (NEC 1100a?). The software that came with the computer is Roxio Easy CD Creator 5.3.4.21 SP28 that I have upgraded with a patch from Dell (R67590). The drive has been tested with DVD's and CD's, and works fine. However, I am unable to format a DVD+R or DVD+RW disc. With the disc in the drive, and clicking on the format button, I get the message: Please insert disc. What do I need to do? Thanks,  Ray
