I played both the Lost World and JP 3 using LPCM over HDMI and there was no problem with the audio. If anybody is having problems, post the point in the movie were the problem is and I will check my copies. I also hooked up my Pioneer 320 to my receiver and played all 3 Jurrasic Park movies using LPCM and had no problem. My OPPO makes my front speakers pop during heavy bass using LPCM on JP 1.
