I just got bunch of dvd-rw from Office Depot, the media code is RITEKW04. The problem is I can only write these discs @2x, I have updated the firmware to 1.08v3-2 (the firmware is downloaded from herrie’s website). Are there any firmwares that support 4x writing for RITEKW04? Thank you.
Strange - I recently burned the same discs in the same drive with the same firmware @4x. These discs were from Platinum.
