I am a long time Tivo user who took the plunge for the HR20 because of the new HD channels available only on the HR20 (Directv DVR). I am just finding out what a big mistake that was!! So before you take the plunge consider this: 1. Missed recordings.. unit has missed 4 recordings this week saying something about the recording being cancelled by someone. During some of those cancellations NO ONE WAS HOME! 2. 50 season passes. There is a limit on the season passes!! Feel free to add to the list but IMHO just the missed recording are enough to go back to the Tivo.
