It seems the Denon and PS3 don't play nice together on DTS. If you take off the DTS setting, then the PS3 will use DD and you'll get surround for games and movies.

The only thing you need is an optical audio cable (toslink) connecting the Blu-ray blayer with one of the three inputs on the AVR3802. Then assign this input in the system menu to the input you like (e. g. DVD) and that should be it. The Receiver automatically detects the sound format from the Blu-ray and changes from stereo to DTS, DD5.1, 7.1 or whatever.

If Denon blu ray has coaxial or optical out for audio, then your Denon receiver will process this signal and will give you 7.1 out sound.

The sound you describe is usually a mechanical noise from the transformer/case work. Home theater amps tend to have quite large transformer in what is, due mainly to its size, a rattly cabinet.

Over time, the lamination inside the transformer can loosen which could explain why it has only just started doing.

Alternatively, one assumes you moved the amp when connecting the new kit? This may have let the case work rest in a new way which is proving susceptible to relaying the vibration caused by the transformer as an audible noise on switch on.
