Hi, I rented Resident Evil Apocalypse, Troy and Harold and Kumar this evening, and had some trouble with RE:A and Troy. When I put the DVD in the tray, and close it, the LG doesn't read the DVD movies. Usually when I insert the DVD movie in, PowerDVD loads up and I can watch the movie. Harold and Kumar loaded up fine, no problems at all. Can someone explain why the other movies won't load up? Thanks.
