Axiom Home Page Forums General Discussion Home Theater Dolby TrueHD and DTS Master HD question

The truth is, there is little audible difference between a well encoded lossy DVD track and the new lossless BD tracks. Only in a direct comparison will most people be able to notice anything. So don't go expecting to hear the same big change as you can see going from 480i to 1080p.

That said, the player (which I'm not familiar with its exact settings) should have an option for LPCM output. Since they Onkyo is only HDMI 1.1 it probably can't decode the lossless formats itself, so "bitsteam" shouldn't be used.
