I just bought me a new Panasonic HD LED TV. THis TV has 4 HDMI ports.

If I connect the surround system and the TV using an HDMI cable then I only have the sound but no video. When I connect a Scart then I have video on the AV1 channel. I suspect the HDMI is simply not working on my surround system.

Furthermore I have a DUNE HD media player and also a WIIU. I would like to connet all these devices using HDMI. I guess yhis would be possible when using an HDMI splitter on the one HDMI port that I have on the surround system ?
