When watching NBC HD, has anyone else noticed that ocassionally the picture goes blurry for a few seconds and then gets sharp again? I've noticed it on both sat and OTA but as I watch Sunday Night Football tonight for the first time on OTA, it seems to be happening far more often. It is not glitchy at all, it just goes blurry for about 2 seconds, then sharpens up again. When watching previously on MPEG4 locals, I only noticed it a few times during the pre-game show. Tonight on OTA, I've noticed it in the pre-game and intermittently throughout the game.
