I had the same experience with Iron Man. It looks as though Iron man only has the HD codecs. They didn't include the standard codecs with this movie for some stupid reason. My PC just sends it out as a 2 channel down sampled signal. This is the reason it sounded bland.
You'll need either a source unit(dvd player) that outputs True HD codecs from the 7.1 analog outputs,so you can run them into your receiver's multi channel inputs. Or you'll need a newer HT receiver.
