What is the difference between "TV Replay" and "Time Shifting"?

Time-Shifting playback is similar to Instant TV Replay in regards to the instant replay capability, but may only be used during Live Recording. Instant TV Replay is specifically for viewing TV but does not record content to a file. Another difference is the recording quality, which is fractionally better, yet at the same time, consumes more CPU resources. PowerVCR II 3.0 still has the "Time-Shifting" feature, but you must turn this feature on by following a few steps:

1.Be sure you are in the "Live/Digital Recorder" mode.

2.Click System Settings.

3.Click the "Recording/Advanced" tab and in the "Advanced Option" section, click "Enable Time-Shifting Playback when recording"
