I agree with jmrobbins.
Over the weekend I installed a new OTA antenna to work with MyHD and my M20X. The nice surprise was how good my analog channels looked in comparison to DirecTv. Over time they have squeezed the bitrate down so much that the picture is not really that good. They sold the service based on it's "digital picture", however, they were less than forthcoming about the bitrates. I have been watching OTA DTV whenever I have the choice. Even if a program is not HD it still looks so much better in digital. Last week I recorded Amazing Race and Survivor using MyHD. While they were not HD they still looked so much better that anything else available. And the fact that I was able to time shift onto my M20X just made me giddy.
I've now decided that my dream box would be an HD Tivo that received AND recorded both DSS and OTA digital. That's a lot of hardware in one box but it would be priceless.
