About the time shift feature
When you watch a live TV program and pause the program, the time shift window appears. As you watch live TV
programming, Media Center is continuously capturing 30 minute increments of the program into a buffer. This enables you
to use the rewind, replay, and fast forward features. When you change channels, Media Center deletes the current TV
programming buffer and begins recording again after a short delay. The TV programming buffer that is captured while you
watch live TV is not saved or stored on your computer's hard disk drive.
