I have a hr20-100 and a Samsung LN-S4695D 46 in HDTV that supports 1080p @60 Hz but I can not get the 1080p on my reciever to work I get no signal to the tv when I try to add the 1080p in the resolutions menu. anyone know if my tv will not support the encoding from directv or is there something else I ned to try oh and I am using a Hdmi cable between them.
Your TV does not support 1080/24p input signals, only 1080/60p, so while you get the progressive scan benefit from video sources (computers, game consoles, and other "video" content), it won't work for film content that is encoded at 24 frames per second (1080/24p). You can still order and watch these movies, but the receiver has to convert it into a format that your TV can accept, and that the chipset in the receiver can output, and the best common resolution is 1080/60i.
You will still get the benefits of the higher bitrate (i.e., less compression, so less macroblocking in difficult-to-compress scenes), but you won't get the full benefit that someone with a "multiple of 24" refresh rate TV could get.
