When browsing around different retailers for the TV, just about all the TVs were showing either trailers or the HD channel. It was quite difficult to fine a demo with analogue TV broadcast and when there was one the quality was poor. On the other hand DVDs look good and it doesn't seem to make much difference if the DVD is copied onto freevo as an ISO image or played with an up-scaling DVD player. A HDMI or a DVI to HDMI converter is important for good picture quality; SCART, S-video and composite connections gives a noticeably poorer picture. It is possible to improve the images by some post-processing. Some old 4:3 TV recordings that have been converted to xvid look pretty good. So quite why analogue broadcasts, which have also the same pixel aspect ratio as DVDs, look so poor needs some more thought. May be because the TV does not have any cleaver scaling and the pixel aspect ratio of 1.4 to 1 gets scaled as 2:1 and 1:1. When comparing the picture quality of TV broadcasts from CRT TVs and TFT TVs the picture quality was simply much better with the CRTs.
