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.
