I got this too on my DVR today. So far I haven't noticed any major differences except the screen color - and one small but annoying problem. Whenever I use the "Prev" or "Next" buttons, it takes an extra second or so for the DVR to seek to the right spot in the program, and another second for the sound to cut back in after the picture playback resumes. Needless to say, this makes scanning thru a program a rather tedious and unpleasant experience. Anyone else out there sharing my pain?
