Thanks for the replies. I am using HDMI. I did select lossless on the bluray disc. However, the receiver still won't give me the option of a lossless codec. I have an extra speaker and am going to experiment with 6.1 to see if it changes the situation.
Just a few points:
- 5.1, 6.1, 7.1 has nothing to do with whether the Denon will show the codec or not.
- If you output PCM to the Denon, the Panny BDP will be doing the decoding and the Denon will not display the codec, but you know that already.
- Selecting "lossless" (as you mentioned) does not mean it is 5.1 DTS-HDMA or DDTHD, I have some live concert BR disc that outputs in 7.1 lossless PCM.
The X4200W is a very competent unit and I doubt very much you could mess up the setting to the point it wouldn't decode lossless DTS and DD if you selected the BDT220 to output bitstream, so double check the settings in the BDT220, I just you re-read page 26 and 38 (see below).
As TLS said in post#12, BD-video secondary audio must be set to off, have you done that yet?
If nothing fix the problem then you should try resetting
both the BD player and the receiver to factory default, that is, perform a microprocessor reset. You can try resetting one first to see if that works.
