How do I adjust the recording start and stop times for a scheduled DVR recording with the Guide?:
Press the LIST button on the remote to access the SHOW LIST screen.
Highlight and SELECT the show you want to change.
Choose ADJUST START TIME or ADJUST END TIME.
Choose the number of minutes before and after the show starts and ends and press SELECT.
OR, go to the SCHEDULED RECORDINGS area (for changes to individual shows or episodes) or the SERIES MANAGER section (for changes that apply to the entire series) and then follow steps two (2) through four (4) above.
