ok great, thanks a lot for the replies. That does help. I've tried "tapping" the diode out of the current heatsink but it doesn't seem to be moving. What have other people done to get the diode out? I know people use a vice sometimes to get the diode back into the housing. Too bad the driver board on the Axiz is of no use, it's nice and small

I'll just have to build DDL's driver.
And one last question, I found this on the drive's website:
"Depending on writing system performance, the drive writes DVD-R at up to 2X realtime. The secret behind the DVR-A03 is two-laser pickup, with a separate laser for reading and writing both CD and DVD media."
That makes it sound like it has two diodes, although I only found one (in the pictures). I did find an interesting microchip with what looked like a lens and/or prism built into it...is it possible that is a CD laser? I thought it looked like a sensor for input but maybe it's actually an output device.
I also found out on a site that they quote the burning power for DVD-R is (for my burner that I took the diode out of) in between only 6-12mw. Does that make sense? It seems VERY low.
