The old software had the option of mapping the HD channels down to the SD numbers. For example, Syfy's HD channel 9432 could be mapped down next to 122. L563 forces the map-down whether you want it or not. You can't disable that option now.
I liked the ability to directly choose the SD channel (e.g. punch in "122" and directly get the SD version of Syfy). I have a old standard TV (in another room) plugged into the yellow video output of the 211. If I know that Syfy is broadcasting a 4:3 program, then the old TV gets a tiny picture with big black bars on ALL 4 sides of the picture on the HD channel, but the picture properly fills the screen when tuned to the SD channel.
Of course I can scroll up or down to reach the SD version after being taken to the HD channel, but I liked the ability (as did my programmable remote) to get there directly.
Am I the only one here who enjoyed the option of NOT having the HD channels mapped down to the SD numbers?
