AIUI you would need an amplifier with an Optical S/PDIF input. I would expect it to work with the equipment that I have, which does not have dolby.

The Vix image has been released and will have been tested beforehand. You can read what people have said in the Vix forum.

If you have not flashed a receiver before, you may find it easier to order a box with Vix already installed (FOC)
