everspiral, if you download PS09 from my site you will find a flashfixed version included in the RAR file that will allow you to flash your Sony to a 160P6S. You can then flash it to the latest firmware.
If you want to use 165P6S firmware to get the DVD-RAM then you can use the flashfixed version in the MS0M firmware on my site, but you will need to upgrade your drive to a 165P6S using the EEPROM Utility to use this firmware.
Michael, can you point me to the thread you started. I must have missed it.
