Every week on The Closer (TNT-HD)--and ONLY on The Closer--whenever there's a black or mostly black screen (during the opening credits; going in or out of commercials; not during very dark scenes) there is massive pixelation. This is the only show I watch on TNT, but I've never seen anything like it anywhere else. And when it's a regular picture there's no problem at all. Has anybody else noticed this? Does anybody have an explanation?
