I have a Dell Inspiron 8500, running WinXP Pro (SP2), with a NEC DVD+RW ND-5100A drive, purchased in Aug 2003. I have never tried to burn a data DVD+R on this laptop (LT) until now. I have played video DVDs and read and written CDs. I recently burned some jpg files to a DVD using Roxio Easy Media Crreator 7.0 on the LT. I put it in my desktop (DT) and was able to display the pictures with no problem. I put the DVD back into the LT and couldn't read it. I burned a DVD on the DT, and it couldn't be read on the LT. I retried a movie and that worked fine. When I insert the DVD into the LT, it just sits there and whirs. After a while I may be able to examine the contents in the DVD (everything happens VERY slowly); if I try to copy a file off, I get the error msg: Cannot copy "filename"; Data error (cyclic redundancy check).
I flashed the DVD firmware to: latest update 10FE at...ftp://ftp.us.dell.com/rmsd/R94927.EXE
This made no difference. I tried using different combinations of the options in Roxio; nothing worked.
To summarize: DVD reads and writes CDs
DVD reads video DVD disk
DVD writes data DVD+R disk (readable on my DT)
DVD won't read data DVD+R disk written on either my LT or DT
