Please help explain to me what this means: Whilst watching 'Superman the movie' on Friday night the players display indicates I'm watching a 'video' source with a small 'v'. The following night I watch 'Superman 2' and the display indicates that I'm watching a 'graphic' source with a small 'g'. What does this mean? Am I set up correctly? What is the difference between 'Film' Video' and 'Graphic' sources. I realise that this is probably a 'tecchie' reply I'm looking for but please try and reply as simply as possible! Cheers in advance. P.s. If it makes any difference, the 2900 is connected by component to a Hitachi 42PD3000 plasma.
