1 - Introduction
This document describes the Digital Video Recorder (DVR) in the America's Guide. If you are not
familiar with the basics of how to navigate in the Guide and the Zap Browser, please refer
to that documentation before attempting to learn the processes outlined in this document.
In this documentation when the word “press” is used this refers to using a button on the remote control.
To highlight something means to use the arrow keys on the remote to select an item in the Electronic
Program Guide so that it is highlighted in yellow.
Symbols/words in this document with color represent buttons on the remote, such as OK for the “OK”
button.
DVRs make "time shift viewing” (watching a program at a time other than when it is shown by the
network) much more convenient, and also allow for "trick modes" such as pausing live TV, instant
replay, chasing playback (where a recording can be viewed before it has been completed), and
skip ahead or back.
DVR allows you to Pause, Rewind and Fast Forward “live” programming almost in the same way
you would a pre-recorded DVD or VHS tape. If you know how to use Pause, Rewind, and Fast
Forward with a VCR or DVD player then you already know how to use these functions with a
recorded program on a DVR. Using these functions during “buffered” recording is a little different.
The next few pages will explain how it works to Pause, Rewind, and Fast Forward with live or
buffered programming.
UNDERSTANDING BUFFERING
You can perform trick plays such as pause, rewind, or fast forward while watching TV, because
your DVR set-top box (STB) temporarily records or “buffers” a program as soon as you change to
the channel. The STB can buffer up to 2 hours of the channel you’re on to enable these functions.
If you change from one channel to another, the STB will empty the buffer and start filling it again
with the programming from the new channel. Using other applications on the STB, such as
accessing the Portal may also empty the buffer.
Understanding how buffering works will help you understand when you can fast forward or
rewind with your DVR. If a portion of the program has not yet run, of course you won’t be
able to fast forward through it!
TIP: After having DVR for a short time, many users will decide to watch very little actual live
programming. Instead they’ll set recordings for most of their shows.
Another technique is to watch “almost live” TV. This is done when viewers tune to a program at its
start time so that the buffer is recording the show. Then they’ll go do something else for about 20
minutes. When they return they’ll go back to the beginning of the show and start watching it. Then
when commercials come up, they have the option of fast forwarding through them. If they were
watching live, they wouldn’t be able to skip the commercials.
TIP: If the hard drive is getting very full with recorded programs, the amount of time that can be
buffered may be reduced.
