This may only affect people with my same setup, or maybe more. I bought Sweeny Todd for a good price and we watched it last night (I had not seen it- it was great BTW), but I got no sound from any channels except the front mains when playing the TrueHD English track. The display on my receiver (Marantz SR8001) showed no channels lit (normal for TrueHD). I had to go to setup and change to DTS reencode in order to get sound. I have watched many TrueHD discs on this player and this is the first time this has happened (it is usually set to multi-channel PCM as my reciever doesn't take THD or DTSMA). I also tried one of my other BH200s and it dd the same thing, so it is an issue with my setup and the disc not this one player.
EDIT: Workaround is to change audio from the player's "display" button and change it back. As I said, it is likely my setup- and it appears to be.
