I've just finished reading this months copy of What HiFi and the budget DVD test, which got me thinking about upgrading my DVD player. I've got a Sony RDR-HX510 which plays at 576p on my Sony KDL40W2000 but I am now thinking about buying the Samsung from the test (HD780 I think). I am using good quality component cables on my Sony player as it doesnt have HDMI output and I wondered if anyone could tell me whether there would be a big enough difference in the picture quality from 576p to 1080p to warrant buying the additional player. Thanks. Matthew
