Not sure if this was addressed or not, so sorry if it has been - could someone post a link to the thread? When watching some digital channels with my 40h80, I notice that some shows, especially HBO documentary shows, are very jerky, almost as if it's out of synch. Since I don't have another TV to compare with, does anyone know what this is or if it's due to my 40h80 or something else? I'm connecting to the cable box with S-video. Thanks in advance.
