OK. I have tried to understand the different setups for the audio signal from my newly acquired Panasonic DMP-BD35. I am using a Rotel RSX-1055 receiver, which lacks the HDMI input. So, the video is sent via HDMI directly to the TV and the audio to the receiver via an optical cable. Settings for the BD player audio signal were set to "bitstream". When I use the BD player to play music CDs, I notice that all signals are handled as 44 Khz or 48 khz at the most, even for recordings at a higher rate. Is this a limitation of the optical cable, the receiver, or an incorrect setting in the BD player? I tried understanding the BD player's manual, but it doesn't help much.

"When I use the BD player to play music CDs, I notice that all signals are handled as 44 Khz or 48 khz at the most, even for recordings at a higher rate."
CDs are 44.1kHz only: What CDs do you have that output 48kHz? Do you have the ReMaster setting turned on? Nearly all movies on DVD and Blu-ray will show 48kHz.
There are numerous 24/96 music DVDs (for example, Classic Records' DAD discs) and DVD-A discs (though some limit the digital output to 48kHz due to copy protection) which have encoded sampling rates of 96kHz. These should be output as 96kHz, unless you limit the digital output to 48kHz.
Sorry, I should have clarified that the CD I was referring to are CD-R of music with rates of 88 and 96 khz downloaded from Linn's online catalog. Please forgive me for my ignorance. I am confused with all these formats, rates, and digital stuff. Can the CD-R be burnt at a higher sample rate than 44 khz? Maybe this is the problem. Movie DVD do read at 48 khz.
Thank you you for your help.
You should be able to bitstream MCH info from say a DVD, DVDA or cable box. I have the Panny 55. I think there are multiple settings for HDMI and other audio outputs. You can turn off the HDMI audio out. I don't think you can record to a CDR in anything other than PCM at 16/44.1. Toggle the panny settings between bitstream and PCM to see what happens. THe Rotel is probably going to sound better doing the decoding instead of the Panny.

I am getting decent sound from the setup I described, I just want to make sure I get the best sound possible. Does anyone know what are the D/A specs in the DMP-BD35? Will it better than the Rotel's?
In reading my DMP-55 manual, it looks like you should try connecting the left and right outputs of the 35 to stereo inputs of the receiver and set the input selector to that input when playing CDs. I know this worked right with my old Denon 3910. Hope it owrks. Good luck.
