Hi again Joern,

So, we know your speakers are connected up to your 861 correctly. Good!

As you're using MMHR from HD621 into 861v6, this is unlikely to have issues, but it is worth trying another patch cable, just in case.

Please do what GlzzE has requested but can you do this on your both Pioneer BDP-LX91 and Sony PS3. This will help to identify if it a player issue or something else.

And also let us know the result from playing your troublesome discs in both of these players, as per my previous post.

Regards,
Carl
