My old DirecTv Ultimate TV receiver grouped the "Now Playing" list into folders. For instance, the list contained an automatically-generated-and-labled folder called "Law & Order", a second folder called "Larry King - Live", and so on. An older-gen TiVo I once saw had a similar grouping feature. My HR10-250 does not seem to provide this capability. I've figured out the "Sort-by" tweak, but cannot find a grouping tweak. Is there a way to install or tweak-for this feature?
