A number of times in the past month my wife has described the following issue while using the HR24-500...... She will be watching a channel and then start to watch a recording. When the recording is finished, the DVR is no longer on the channel she was watching before playing the recording. There are no recordings going on during this time, btw. Often she will start watching local news, then when a news story comes on that is of no interest, she will start a recorded show. Then, when the recording is done, she wants to review the rest of the news quickly. I know she can hit record before leaving the news, but she doesn't always remember to do that, and we never had to do that with our HR21-100, which this HR24 replaced.
