OK I had the same issue with my SH-222BB, I managed to get it working. 1. Update the DVD R/W firmware (not sure this was the most important part though, but do it) http://www.samsungod...lue=view&no=782 Firmware updated from SB00 to SB01. (reboot) 2. Update your chipset's drivers (probably what people do when they install Intel RTS) You can try to auto detect. http://www.intel.com...support/detect/ Didn't work for me. I had to get it manually. Got an ASUS P8Z77-V_LK, updated to Intel_Chipset_V9301019_LK_XPWin7.zip from Asus website. Reboot, reboot again, all good.
