When watching wide-screen DVD's (is there any other way!) on this Sony set,the horizontal scan lines just below and above the black bars on the right side of the screen bow toward the picture.(the last 1" or so) It's about 2 to 3 lines worth that are not part of the dvd picture therefore there are red,blue or green dots that are not suppose to be there. On full frame images there are no problems. Currently I use mattes placed far enough into the picture to cover up this flaw,however I am looking for a long tem fix if possible. Any thoughts?
