What are the correct and most trouble free speed choices when installing the modded DS1E firmware from codeking's website (patched - faster DVD R / RW/ DVD9)?
16X DVD +R16x DVD -R8X DVD RW8X DVD9
I've found mine seems to be best at 14x or less, at least with burned media. Some drives do better I guess but mine is not one of them and the one before it wasn't either. Try the options and see what your drive likes just in case you got a super perfect drive
