So far I have found the 42LD450 for be a brilliant TV, and while I dont have access for any HD channels, I find that the overall quality in my older DVDs seems better, they seems more clear and sound better, whether this is just my imagination im not sure but as I say, im impressed with it.
The setup was a doddle as with any LG sets, just plug in all your connections, do a quick scan and you're away to HD bliss. I would recommend the LG 42LD450 to anyone
