Satellite is an all digital signal. Cable is analog or you pay extra for a digital signal. Digital is a better choice but soon,and i'm sure some one will state the year,2008-09-10, all broadcasts will be in digital format. As for the poor picture display. If all channels but ESPN are clear then I wouldn't think it's the set. But then again LCD is not a good choice for fast moving displays such as sports. So i've read here and on other sites. You don't say if it's during a game or if it's also happening during comercials or commentary. Now as far as longevity. Plasma is rated as high as 60,000 hours of viewing capacity. The most i've seen for LCD is 20,000 hours.
I have a Sony KDL-46XBR4 and all of the HD channels look blurry.The sports,shows,and movies blurry and very pixalted and I see the triple image effect sometimes but, only on ESPN.The TV looked amazing at the store when they were showing spiderman 3 on it so I know its capable of showing great picture quality.How do I know if its the TV or the satellite provider that gives me bad picture quality?For video games it look awesome.I was thinking of replacing the Sony for another one of the same model or get the Panasonic 50pz700u.But I hear that LCD's outlast plasma's is that true?
