Just installed this today, no problem with CD's but when I play retail & copied DVD's I get sound but no picture. Have tried with Windows Media Player 9, PowerDVD and WinDVD 5 and have the same problem each time. Have also tried with Nero 6 Showtime but just get 'Internal error. Cannot build graph. The application may be installed incorrectly.' I have rechecked my hardware connections, Windows XP tells me all is working correctly, and I have downloaded latest firmware from LITEON.
I would be grateful for any suggestions because this is all unknown territory for me, is this a software/driver issue or might there be something wrong with my new equipment?
