After five days I have a handle on the HR20 versus the 10-250. I miss Tivo software. I never liked the DirecTv guide grid but that's all that is available. I miss dual buffers and season pass type recording is not as good. Both receivers suffer from bugs. The 20s menu is much faster than the HR10 and it is nice to have a picture while working with the menu. One touch recording is faster with the 20. The 20s OTA tuners seem to provide a better picture but I did not do a side by side comparison. Overall, while I prefer a Tivo based machine the 20 is not the disaster that many believe it to be. It is far from perfect but has potential if they continue with regular software upgrades.
