I just updated my system and am now a bit confused. The old hook up would display a red bordered "Dolby Digital" box when playing DVD or recieving the proper signal via the cable box. The new set up has a LCD 46" 630 Samsung series TV. I have an HDMI cable from the cable box to the TV, an HDMI cable from the BluRay to the TV and an optical cable from the TV to the TX DS575 reciever. I no longer get the red box, I now get "PCM Digital" and Dolby Pro Logic" displayed together only. Is this typical, good, bad? I have not been able to find any info on this.

If the display is showing as optical/PCM, then the input signal is in 2 Ch Stereo.
Try to change the signal from the source i.e. the DVD player, On the remote, go to audio and press repatedly , the audio would change from audio1, audio 2 .... and so on, depending upon how may have been recorded on the DVD. If the DVD is recorded in Dolby Digital, it may show the audio as Dolby Digital 5.1 on you monitor. Once this setting has been done, your Receiver should automatically detect it and show as Optical/Dolby digital.
DTS-HDMA and Dolby TrueHD cannot be passed to your receiver via bitstream on the PS3. DTS-HDMA cannot be decoded either so you're out of luck there.
Dolby TrueHD can be decoded internally on the PS3 assuming your firmware is up to date. Set the Blu-ray HDMI output to PCM and you can then pass it to your receiver.
If this doesnt work, do a system update on your PS3.
Hi, no, this is not the normal display. It should indicate the digital sound format like DD or DTS, etc. If it is displaying PCM, this is probably due to the audio settings on your DVD player. Please provide your DVD make and model, and I will look to find the solution.
Chances are that Time Warner is just plain wrong. That's what you get with free tech supp....oh, uh right. scratch that.
Your receiver seems to be receiving a 2-channel digital audio signal (PCM) from the cable HD box. With this type of input signal, you can't select Dolby Digital on the receiver.
If you have a Scientific Atlanta 8300 (or a closely similar model): Press [Settings] button on the remote twice. This will open the General Settings menu. Go to "Audio: Digital Out" and the select Dolby Digital (by hitting [-> Move Right]).
If you have another type of cable box, just review the settings menus until you find something relevant to digital audio out and avoid PCM, stereo or "down conversion", but look for Dolby Digital, DTS or "All".
Please keep in mind, that when connecting devices via HDMI cables, your box may decide it's smarter than you and reset the format of the digital audio back to PCM. This is some possibility of this occurring if the cable box or TV is unplugged and plugged back in.
If you have problems, add the cable box make and model and let me know.
PCM is standard when using HDMI cables, you are passing an already decoded audio signal to the receiver and it outputs the sound and does nothing more. The reciever calls this PCM, your PS3, when pressing select should show that it is decoding the dolby digital HD. There is no quality difference in the two. PCM is the same because it is un compressed audio. So when using HDMI, no matter the signal that the movie or music is playing, wether it be dolby or DTS, you will see PCM when using HDMI.
If it is a new DVD that may be a problem, as signal changes may be frustrating this old machine... but it is likely the cabling from the DVD player to the reciever. Are you on the right channels/settings? is the optical cable and digital cable recieving digital output from your DVD player? Try changing those settings and you should be in good shape
Thanks! good luck!
