I recently purchased a Sony STR-K502P A/V receiver. I have a Direct TV and a Sony DVD player going into the 2 optical audio inputs. The receiver has a Automatic Detection button that is supposed to correctly recognize which type of signal is entering the receiver. However, it is not doing this. When the Auto Detect button is selected the surround display shows L and R only. When selecting the Normal Surround Mode using the Optical input the receiver only shows that the signal is Pro Logic and not the DTS or DD 5.1. I have made sure that the DVD player is selt up to output either DTS or DD but the receiver refuses to recognize the proper surround setting, nor does the blue light on the front panel activate showing that it is receiving multi-channel audio. The speaker display only shows L,C,R S and SW. The DVD's I'm using are current release movies (Moulin Rouge, Matrix, Tron Anv. Ed.) and are encoded for the surround sound. Any help would be appreciated. Thanks

Will try to help if possible. I'm using Yamaha so I'm not familiar with Sony particulars. With my setup in auto mode it won't select dts but only DD or pro logic, so have to set dts manually.
Have you tried using digital connections not optical, and if you have are you experiencing the same results?
Also do you have analog rcas connected? It could be a faulty unit but it's pretty unlikely.
With a little more info we can probably narrow it down.Semi
Yeah, my limited experience with the same problem the original poster describes (different gear though) was due to my DVD player not set up to put out RAW digital data for DVD's. The manual was very unclear on this, but I can sum it up as to not put out PCM (wish they had said this). Whatever I set the smart decoder up to, with PCM input it always refused to give 5.1 or dts sound. Good luck, I'm sure your gear is good, just need to figure out the right communication.
anyone has a manual ?
my box didn't have one

I had this problem as described above with my Sony STR-K502P receiver which was part of the HTD-DW830 Sony home theatre system.
But the cause was that the LG DVD player a DVD-2360P had a default setting of Dolby digital on it's Digital output ports.
I had to go into the Setup menu on the DVD-2360P on page 37 of the users manual and change the Digital audio output to Stream/PCM from the default setting of Dolby Digital/PCM once this was done and the setting saved full DTS Audio was enjoyed from the home theatre system.
The Sony STR-K502P even auto detects the difference between Dolby Digital and DTS Digital Audio if either the Co-ax or Optical links are used between the DVD and the Receiver.
