Hi all, I have purchased Sony DAV DZ610 to connect with me Sony Bravia KLV 40EX400 LCD HDTV. But I can't happen to play 720p or 1080p mp4 movies on it. It says video frame rate or nitrate not supported. Is it that it isn't built for resolutions higher than DVD? If this is so, which Sony HTS model can play such movies? Looking forward to ur response!
