This will be a totally techie comment, but I’m so surprised by something I’ve got to explain it. I have a Verizon FiOS Motorola QIP6416 DVR set to 720p with an HDMI cable going to my Panasonic video projector. HDTV looks wet-your-pants fantastic. SDTV is rather disappointing, and I avoid it.
I have a FiOS Motorola DCT-700 digital/analog converter with a cheapie RCA composite video cable going into a Panasonic DMR-ES15S DVD Recorder that’s set to 480p. From there is a 12-ft component video cable going to a Kenwood THX receiver that has a 50-ft component cable going to the projector.
There is absolutely no comparison in picture quality. The bottom-of-the-line DCT-700 going through the recorder and the receiver totally blows away the video going directly from the top-of-the-line DVR over HDMI. Savvy techies would say “no way!” but I’m telling you definitely yes.
