The native drivers for XP are fine & I don't recommend upgrading - yet.
The Lite-On likes to be master, so swap it around. Upgrade the FW to the latest - tested & is OK.
Disable the third party burning software. In any event Do Not install the burning software update from MS - it does dreadful things to other burning proggys & system stability.
You may have to disable IMAPI services (recommended by SwEnSkE & VeNoM386 at the Daemon's Forum).
Disable AIN & any disc detection software (e.g. Creative disc detector).
Get away from safe mode
