In order to bitstream lossless audio, supplemental audio/secondary audio, must be disabled otherwise the lossy track will be bitstreamed. All of my BD players work this way (Sony, Panasonic, Samsung). As to why Sony decided to only do two channel TrueHD decoding this year on all models, whereas last year it was only on the lowest end model, one will never know. It does create a problem when mixing in the secondary audio. I for one, don't use it.
