GSA-4167B system reboot w. DVD-RAM

I have experienced sudden re-boots of my PC (XP SP2) when trying to play a DVD-RAM disk recorded on a Samsung DVD-VR355 - it happened three times today with the same disk. I can play this disk on my other DVD (Matshita DVD-ROM) drive without a problem (using PowerDVD in both cases).

Some posts have mentioned power supply problems with this LG writer - is my power supply perhaps too weak? I have lots of USB devices hanging on my PC.

The only other problem sometimes experienced with the LG is with some copy-protected PC games - the drive light goes on and off endlessly and never starts to read the disk

The firmware version is DL-11

Please don’t cross-post the same question. Your other thread in the LG forum is deleted.
