I have a Lenovo 3000 v100 laptop, about 2 years old, running Windows XP.
It came with an LG DVD/CD RW combo optical drive. Worked fine until recently.
It currently reads and burns audio and data CDs fine.
It will not read or write DVDs. When I try to play a movie DVD with Intervideo WinDVD, I get an error like "Intervideo WinDVD encountered an error and needs to close."
It will also not read with Real Player or Windows Media Player -- I get similar generic error messages.
I have tried different DVDs, including homemade ones and professionally produced ones, same thing.
I can open the DVD folder and see the video files, but they won't open. I can copy the files to my hard drive, but they won't open.
One DVD, "Closer," the opening menu starts up, but it won't move beyond that to play the DVD.
I updated the BIOS from Lenovo's site, no change.
I deleted the upper and lower registers, no change.
I tried deleting and reinstalling the drive, no change.
I physically removed and reinstalled the drive, no change.
Assuming the drive was defective, I bought a new Samsung drive and installed it, same problem.
I don't think it's dirty DVDs -- they play fine in my other DVD players.
Hard to believe the second DVD player was also defective, but I guess maybe...
