I just bought a BDP 7700, connected and turned on.
When I first tested it, I used a BD with DTS-Audiotrack, but my AV-Receiver just shows "multichannel". I also use a Multimediaplayer for streaming, but it has a BD too. When I play the same track, the receiver shows the correct content, DTS.
I cannot find the mistake in the 7700, but there is no mistake in the receiver either.
Do you have a hint to solve the problem?

Thanks
