I have a Lite-On DH-20A4P-04 which I installed in my Dell 8400 with Windows XP. It will not read any DVD’s. It does fine with CD’s. I have updated the firmware to the 9P59. Same problem when using the 9P54 FW.
Just need to read a DVD, not trying to burn. I use latest version of WMP and don’t have any special DVD software except the original Cyberlink PowerDVD 5.3 software which came with my Dell 8400 computer. Could this have something to do with my problem. Neither one will make it read a DVD.
Any ideas what my problem might be?
