No worries, if you don't know the terminology, it can all be a bit baffling. In case you're not sure, basically the BD50 has 6 multi-channel outputs on the back which I think are on the far right of the player and are labelled Audio Out and then each one will be labelled for each speaker i.e. Front Left, Front Right, Center, Rear Left, Rear Right and Subwoofer. You should also have corresponding inputs on your Denon amp so you merely hook these up as Gerrard says with 6 standard RCA phono leads.
You can then set the Blu-Ray player to decode onboard and output the sound over the multichannel outputs and set your amp to the multi-channel input and you should then get HD audio. This is because the standard optical and coaxial outputs aren't able to send the full HD audio soundtracks out as there isn't enough bandwidth. However, by setting it to decode onboard and export via analogue, you can get this.
Let us know if you need any further help.
EDIT - looking at a pic of the back of the Denon 1907, it looks like the multichannel inputs are on the bottom left, labelled EXT. IN and then corresponding letter(s) for each speaker. The Denon actually has 8 inputs (for 7.1 signals) so you don't need the SBR and SBL inputs which are for the surround back speakers present in a 7.1 system. Since the Panasonic only has 5.1 output, you can't use these, but that doesn't really matter since there are very few native 7.1 soundtracks anyway.
Right then, this could take a while.
I've got my Phono leads and got them all hooked up FR/FR, FL/FL etc but now comes the difficult bit of setting it up.
I've got the following 4 options when it comes to the sound setup on the blu ray:
Dynamic Range Compression - On, off or Auto
Digital Audio output - This has a sub menu which consists of Priority setting which is either Secondary Audio, Audio Quality or User
PCM Down Conversion - On or Off
Downmix - Stereo or surround encoded
Where do I go from here?
And I can't even begin to find out where to change the Amp to play the Analogue input.ÿ
On your receiver (and I'm going by the 1908 here as I can't find the 1907 manual) you need to change the input mode to EXT IN.
On the Pana settings. You need the Speaker to show Multi Channel and the hdmi audio output needs to be set to OFF.
Your other audio options should be set to Auto for Dynamic Range, Digital Audio - OFF. PCM Down Conversion - OFF and Downmix - Surround.
