I'm trying to replace the DVD drive in my old PC. LiteOn.com is a mess and I can't find a single working driver or firmware update there, or anywhere. Windows XP tries to use a default, generic driver dated 2001. (About 9 years before this drive even existed.)

http://www.firmwarehq.com/download_1..._6L0H.EXE.html

This correctly finds my LiteOn ihap-122-9 DVD Drive.

It correctly finds that I'm currently using firmware 6L0F.

It correctly tries to install 6L0H.

It completes 100% but then just fails and says "contact your vendor".

Does anyone know why?

Where can I actually get drivers... and firmware updates... that actually work for the ihap-122-9?

Apparently, the newest driver IS the 1 made 9 years before the drive existed. (Unbelievable.) And the latest firmware is the 1 that is already in the drive. (Common.)

No other drive I've had in this computer ever had a problem. This brand new LiteOn is doing this:

• Opening MY COMPUTER now takes 60 seconds.
• MY COMPUTER marking the drive as "DVD F:" takes another 30 seconds.
• MY COMPUTER showing "Batman II" title takes another 15 seconds.
• Clicking and running the movie will take another 30 seconds for the main-menu to appear.
• The movie starts about 20 seconds later.
• The movie runs fine for 1-2 seconds... then stops for 5 seconds.... then starts again and plays for 1-2 seconds.
• Repeats for 2 hours.

(It happens with all store-bought DVDs and all home-made DVDs.)
