Just a follow-up Gonk when my sister sets her BDT-210 to bitstream she doesn't get any sound but if it's set to PCM she has sound does this make sense?

Unless there's some other setting keeping bitstream from working sounds like she has no choice but use PCM I hope she's getting Dolby 5.1 not stereo.

Since she's using PCM do any of the other audio settings mentioned above change?
