Thanks jds63, it fixed my problem. Dvd drives are up and running.
Might be what you are talking about with the registry fix, seen it used in the past for similar issues not reading discs.

Similar way to, but also reinstalling the disc drive in device manager to
1) click the start menu
2) click on "run"
3) type "regedit" and click ok
4) go to string key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
5) delete "upper filters" and "lower filters in the right side window.
6) right click my computer in the start menu.
7) click properties
8) go to the hardware tab
9) click device manager
10) expand the dvd/cdrom drives
11) right click the dvd rom and click uninstall
12) restart computer
Other cause can only be DVD drive has a CD laser diode and a DVD laser diode one could be bad. Be if only DVD do not read.
That's good you picked up from another post, just thinking it when i seen it, YW
