Hi everyone, this is my first time here. I've searched and read a bunch of threads b/c I've been unable to burn my Ritek (R04-001) 16x +R discs with my 4163B using both Nero 6 and Easy Media Creator 7. Seems that they are just burning at default 4x speed. I've tried with firmware A03 and then updated to A04 and still no luck, which is strange b/c R04-001 seem to be supported by A04. If anyone has specific experience with these discs with this drive, please help me out. Thanks!
