Well, although I'm sure it's close, I don't know that I would go as far as saying "just as good". As soon as you take something from lossless to lossy, it's never "just as good". Especially if it's a 7.1 source that is downconverted to 5.1.
Here are your options:
- Turn on bitstream and let your receiver do the decoding. This also means that you can simultaneously output the core lossy Dolby Digital or DTS track via digital optical or digital coax. This is the only option I have for running D-BOX.
- Turn on secondary audio to LPCM and let the player do the decoding of the lossless track, add the secondary audio like PiP Commentaries and menu sounds, then convert it to LPCM. In this scenario, there is no loss of sound quality and everything remains lossless.
- Turn on secondary audio and let the Oppo decode any lossy track, add the secondary audio and then convert it to lossy (but high bit rate) DTS. Your receiver would then decode the high bit rate DTS. This is a LOSSY signal and I have no idea why anybody would EVER use this when they have option two above.

No need to wonder. The decoding of DTS-HD MA or Dolby TrueHD is exactly the same whether it's done by the Oppo or by your receiver (as long as everything stays lossless, it's all the same). Here's an analogy for you: Take a .zip file and unzip it using WinZip, Windows, or 7-zip, you're still going to get the same files in the end.

I used to think that too, but LPCM sound quality is the same as DTS-HD MA or Dolby TrueHD. Now, your receiver may have different post-processing options based on the format of the original encode, but I leave all of that stuff off anyway.
