I have a Panasonic TX-L32DT30 which I'm generally very pleased with.
HD has just been switched on in my area, so I retuned and picked up all the new HD channels.
However, flicking between BBC1 and BBC1 HD gives not really massive difference in my eyes (or indeed, my wifes). I'm guessing that my TV is upscaling the SD signal so the difference is much less - a better test would be to turn off upscaling (something I'd not considered by typing this - I'll try it tonight when I get in). Anyone else rather underwhelmed by HD?
