Does anyone else out there see an amazing difference in picture quality between the HR10-250 and the H20. I know about MPEG2 vs MPEG4 but am shocked at how much better my picture looks with the HR20. The off air receiver sensitivity is not even close. With the H20 using my large outdoor antenna, I'm picking up every station in HD and usually with a 95 or better signal. With the HR10-250 I get nothing. I love my TIVO but seriously considering going back to the H20 with the better picture on both standard and high def channels.
