Both output options are technically bitstream. Also, as I said before, I know that the optical doesn't have the bandwidth to support the lossless HD formats. That's kind of besides the point. The "Bitstream Audiophile" option outputs main feature audio stream so my receiver does the decoding. I'm assuming DTS-HD will just be downsampled (downmixed?) to DTS, Dolby TrueHD to Dolby Digital, etc. by my receiver. However with the "Bitstream re-encode" option, the disc player is decoding and then re-encoding everything to DTS bitstream. I'm wondering if there's a quality loss there.
IE: If the movie's main feature audio is in Dolby Digital, but I have Bitstream re-encode selected on my Blu-ray Player, my receiver will actually be receiving a DTS bitstream because of the re-encoding the player did before passing the signal out. That's really not necessary other than to get some PCM audio mixed into the stream (for nav and extras), so if it effects quality, I'd rather not use it. It really comes down to the quality of the decoding and re-encoding to another format (in this case DTS) within the player itself.
Is anyone following me?
