Last night, I was recording the football game on ESPN HD. The recording was set for 3 hours from 7:30 to 10:30PM. Realizing that the game was going to go over, I went into the menu and extended the recording for another hour. Several things happened: When I went back to watching the game via the recording, the time bar on the bottom of the screen still only showed 3 hours, not 4. I had to exit the recording, and then restarted the recording from the beginning. Only then did it display 4 hours. So, I thought everything was fine, so I left the room and went to do something else. When I came back later, it stopped recording at 10:40PM, 3 hours and 10 minutes into the program. For whatever reason, it just decided to stop recording 10 minutes into the extended buffer time. Not sure what I would have done wrong and thinking it's just another quirky bug with the HR20.
