3 Cheers - you'll be busy, what with the CS0C codes fix for Omnipatcher as well.
How far do you think you can get?
100% proper Liteon, with the Red, Orange for underrun etc. or just a cosmetic swap to red (Not flashing, please, that would look like an error) while burning.
The annoyance with the Liteon to Sony change, is not so much the colour, but the loss of feedback - eg. the difference between the red-green flicker of power calibration (on my old CD-RW, that was usually a bad sign, if it took longer than usual), and the solid red of burning.
