Not sure if this is a H/W or a S/W issue but figured I would start here. Just built myself a new system: - Windows XP Pro 32Bit - INTEL CORE I7 920 2.66G - ASUS P6T 1366 X58 MB - 2GBx3 (6GB) OCZ OCZ3G1600LV6GK - ASUS EAH5770/2DIS/1GD5/V2 Video Card - ANTEC TP-750 750W PSU - BD-COMBO LITE-ON IHES108-29 - Plextor DVD-RW PX-806SA - 2x 1TB SEAGATE 7K ST31000528AS OEM - Sound Blaster Audigy 2 ZS Platinum - 2x Syncmaster 930B Monitor (D-Sub Connected) Downloaded all the Windows updates, driver updates, software updates, etc. that I could find. The system runs great except when it comes to playing Blu-Ray Movies. When I play a Blu-Ray Movie, all the intro stuff is fine but when it gets to the actual movie, it plays nicely for a few seconds and then gets very jittery, both audio and video. The picture does not break-up or pixalate just very stuttery, jumpy, jittery, is the best way I can describe it. Roxio Cineplayer BD Ver 5.3 is really bad, Cyberlink PowerDVD BD Ver 7.3 is better but not great. I have run the Cyberlink BD Advisor and it come back and says my Graphics Driver doesn't support Blu-Ray but when I check the details Cyberlink says Recommended driver version: 8.44 or later, I have 8.670.0.0. BD Advisor also has unknown by the CPU and Graphics Card (i7 920 and EAH5770). Anyone got a clue why my Blu-Ray Play back is so crappy? I am wondering if the ASUS EAH5770 really does not do for Blu-Ray? It is supposedly HDCP Compliant. Also, my Monitors (SyncMaster 930B x2) only go up to 1280x1024, so I know they can't do full 1080. I initally tried hooking them up via DVI but that definitely didn't work, so I switched back to VGA cables (D-Sub) connections. The monitors I don't believe are HDCP compliant. I can't believe the monitors would cause the audio and video to both be jittery. Any help with figuring out why my Blu-Ray playback is so bad would be greatly appreciated. Thanks.
