I've just purchased and installed a Pacific DIGITAL DVD Writer and it runs well however, I have a Yamaha CD re-writer that I use as a cd-rom to play GAMES. I do not want to use the DVD writer for all functions available because I feel that it will shorten it's life. The problem is that when I put a game DISC in my Yamaha and click the icon to play, a blank white screen comes up without showing the disc's contents. The Yamaha does show up in Device manager but I can't seem to get the drive to function. My guess would be that the Pacific Digital has chosen itself as the propriatory drive. I contacted Pacific Digital support but received no answer (Not Suprised) Thanks in advance.Have you tried updating your DRIVERS? Also, which operating system are you using?

[glb]Flame[/glb]Same exact thing happened to me, had to unplug computer and reboot.  Matter of fact, have to do it everytime I use the burner.  I tried PD an Iomega DVD burners.  Had problems with both.  I finally returned them both and bought a Sony DVD burner (external) it works great!
Are your Master an Slave connections right? Just a thought.
