My folks just picked up a 42" LG LCD. They bought the HDPVR along with it (HD cable box), connected via HDMI. They had me take a look @ it and set it up, because this was clearly a daunting task for them. After it was all said and done we watched a few programs........and im unimpressed with the PQ......it looks blobby and pixelated, as though its receiving HD channels in SD and blowing them up, i've completed the cable box setup wizard......i can't find any settings on the TV that would account for this. The only thing i could think of that would be causeing a degraded picture is the HDMI cable......although im aware that digital signals shouldnt be affected a great deal by a cable.....its all i've come up with. I supplied the cable for them which came with my Panny DVD-S77 so they wouldn't have to fork out an extra $130. Has anyone had a similar experience with this particular brand...or LCD in general? Am i missing something? Any help is greatly appreciated.

p.s. i tried using component cables just to see the difference....and the picture looked wretched....unbareable to watch, someone reassure me that the HDMI cable isn't causing this.

Thanks!
