I thought that Tivos were always recording what you were watching and so if you decided to press 'Record' near the end of a show it would automatically save everything that you had already watched up to that point (in addition to recording the end). So if you were half-way through a movie and, for instance, decided to go to bed early, you could press 'Record' and walk away. Next day your Tivo would have the last half of the movie plus everything you'd watch previously. Now it's not doing that. It's only recording from the point where you press 'Record'. Am I imagining this or can other people confirm?
