Tynamouse

So, I have been trying to figure why my picture has many probs. My 70" sony was damaged and has been worked on a couple of times including a new optical block.Sports by far look the best. Lots of high def shows have motion blur or just are not very sharp. Again, it depends on the program. Are these the type of symptoms that you are referring to? I have a hr 20 dvr. Are any of the newer models better?
