I have a HR20 hooked to my 27" Sony in the bedroom. I am useing the s-video connection, set the resolution to 480i, and output ratio to 4:3. I letterbox the HD channels unless it is not a widescreen program, then I use 480i crop which fills the entire screen like a normal 4:3 channel but it looks better. The SD channels work the same as always. Hope that helps.
