Hello, I'm having trouble watching blu-ray movies in 3D on my HTPC. After about 10 minutes the audio and video become out of sync, if I pause the movie for a brief moment and resume play if corrects this problem but then happens again after another 10 minutes. Regular blu-ray disc play fine, this only happens when watching a 3D blu-ray. I have a GTX 570 in my HTPC hooked directly to a 55" Sony KDL-NX720 thorugh HDMI. I often use headphones though my sound card, a Creative Sound Blaster X-Fi Titanium Fatal1ty Professional series. When I have my Asus VG236 monitor hooked up through Dual Link DVI this audio / video sync problem doesn't occur. I've searched all over for a possible solution but haven't had any luck. Iv'e tried two different programs for playback, PowerDVD 11 and TMT5 and still the same problem. Please, any help or advice would be much appreciated! Thank you for your time

Have you tried sending the audio over HDMI? I would imagine that should work.
