Hi, please bear with me with this post as I have a lot to state. I've recently installed an LG GGC-H20L (the HDDVD/Blu-ray reader) into my computer and I can't seem to get blu-ray disks to read properly. After a lot of tinkering I managed to get HD DVD's working fine but blu-rays very rarely work (they have worked once or twice which leads me to believe that the drive is working okay). My specs are: AMD X2 4400, 2GB RAM, 8800GTX, Asus A8N-SLI Deluxe MB, Vista 32-bit. The computer is connected to my monitor via VGA, and I know that you DON'T need an HDCP monitor right now as most disks are not encoded with that measure (and the fact that I've got the drive to playback sometimes means that it works through my VGA). What I've done: I've tried a few BD players such as the packaged PowerDVD Ultra 7.3 and WinDVD 9 and also with AnyDVD enabled. I've upgraded to the latest PowerDVD 7.3 and I've patched with the LG update. The firmware for the drive is the latest v1.03. I've changed the interface controller from DMA to PIO in Windows. I've even bought a new SATA PCI card which didn't solve the problem and yes I've tried other SATA ports. I have a normal SATA DVD burner that worked first time so I know that the SATA controllers are working. I've disabled DEP for the BD players and turned off Visual Themes for them too, disabling autoplay for the players today seemed to have helped a little with the disk recognition. I've got two double-disk blu-ray titles that I've tried: Transformers and The Golden Compass. When I first installed the drive the second Transformers disk usually worked but the actual movie disk didn't. That changed today when my computer actually played the film but when I tried changing scenes the program locked and crashed. That's the only time that that disk has worked. Now I've tried it and sometimes AnyDVD says that it's scanning the disk but it'll go on for some time (more than a minute or two) and then nothing. This event happens on and off, most of the time the drive light upon inserting a disk just blinks on and off (sort of to every second) for over a minute and then just stops. I've tried to read and do so many things and still blu-ray doesn't work. It's really driving me crazy, especially when other people have said that they've managed to get the drive working first time. Anyone out there have any ideas?
