"Detected DVD-R as 4x but write at 2X"1.5 starson
Summary: Everything is OK but wait til you use media 4x. It will detect at 4x but will write at 2x for some media. You're lucky if 4x Ritek or 4x Princo will burn at 4x because these are not Sony recommended but are common cheapest brand that we can afford. I have DRX-500ULX and I'm reading from internet forum the DRU-500AX shows the same problem. I'm sending this message to everybody so that you can save time and effort troubleshooting the problem. Your PC hardware and software has nothing to do with the problem and it's definitely the drive. Newer firmware version 2.0f will not solve the problem either.
