How do we reverse a movie like on HBO when we turn it on and its half over?
The only way to do this is if the channel has been captured in the buffer. If it has, hit the "Record" button while the channel is displayed. The movie should start recording, and the buffer will be captured. Then go to the DVR and select Play (from beginning). With the newest IMG (1.9.7), if the movie is in VOD bringing up the guide and hitting the left button should take you to the selection in the VOD area and you can watch it there.
