Cross flashing dvd burner

I recently came across an old thread that explained the process of flashing a phillips dvd±rw 8801—> into a benq1650. since I have the dvd8801 im interested in doing this but don’t know what there is to gain. I’d appreciate some help and I am aware of danger of damaging a working burner. I have flashed cell phones before, not knowing what I was doing and simply following these great tutorials found in these type of sites. btw this is the thread:

reason I want to flash is to change booktypes on dvd+r media that doesnt play on my old ps2, i see on imgburn that benq is one of the drives that allows you to do this

no disc in drive follow instruction :-), no threat but there is always risk
