In order to get the flexibity I need, I've had to put an Octava 5x2 splitter unit in front the of my HD621 for some of my sources. One of the mirrored outputs goes to my TV and other to the HD621 for the sound (and projector when used).

I was expecting a load of HDCP issues - but nothing - it all works perfectly - amazing!
