I reecently took delivery of this set and overall, am very pleased with it. I am having trouble with DVD replay though. I am playing DVDs on a Denon 3910 @ 720p over an HDMI cable connected to the Panasonic. The picture looks great but is not coming close to filling the screen, there is a 10cm border all the way round. I have been through both manuals but haven't found anything that helps in either of them. Suspect I am missing something simple - any thoughts or advice would be greatly appreciated.
