Not sure if this is home theater in a box.
First one is lip sync problem with my ps3 every blu ray movie has this problem iv tried av sync on and off. Iv tried setting it from bitstream to lpcm and also unplugging and switching hdmi wires its still hit or miss.
Second when playing a video dolby true hd. I benefit more from setting the ps3 to Lcpm and having the ps3 convert and send to sub via hdmi cable correct? On the movie menu it shows dolby true HD.
