Ok, just an update :

I bought a ByteCC USB 2.0 + FireWire enclosure and I've managed to install it around the Liteon burner. I tested it by connecting it via FireWire to a computer (not my laptop) and it detects fine. I haven't yet fried a dvd (because all the data is on my laptop) as I'm waiting for a 6 pin to 4 pin firewire adapter to arrive sometime next week. Meanwhile, I also successfully patched the 812SX to 832SX.
