Validation results
When you open an audit trail, the Safeguard Desktop Player checks if you can access both the upstream and downstream traffic from the audit trail (you must have access at least to the downstream traffic to replay the audit trail), and validates the digital signature and the timestamp. The 
icon means that the trail is not signed or timestamped. For details, see "Validate audit trails" in the Safeguard Desktop Player User Guide.

Language
-
Safeguard Desktop Player application language: Set the preferred language for the menus, buttons, and other controls of your Safeguard Desktop Player.
For the changes to take effect, close and restart the Safeguard Desktop Player application.
Graphical protocols
-
Keyboard layout: In some cases, RDP and ICA audit trails do not contain their specific keyboard layouts. To avoid misspellings in the subtitles, you can set your specific layout for all your audit trails.
For each individual audit trail, you can still override these global settings from your Details page of your Safeguard Desktop Player as shown in the example figure below:
Figure 3: Safeguard Desktop Player > Details page > Changing the keyboard layout for individual RDP or ICA audit trails
-
Window title: Select how you want to display the window title events on the seeker and in subtitles.
-
If your audit trails are indexed, select Only indexed trails (faster). Indexed audit trails already contain the window titles, and the process of displaying the window titles is faster.
-
If you are unsure if your audit trails are indexed, select Always. Safeguard Desktop Player detects if your audit trails are indexed. If no indexed audit trail is available, Safeguard Desktop Player will start indexing the audit trails automatically.
-
If your audit trails are not indexed, select Forced detection (slower). The audit trail will be re-indexed, regardless if it had been indexed before or not, and as a result, the process of displaying the window titles is slower.
-
If you do not want to display window titles, select Never.
Terminal-based protocols
-
Terminal encoding: The character encoding of the displayed text on terminal-based audit trails, for example, SSH, Telnet or Sudo iolog. This selection will be your default encoding.
For each individual audit trail, you can still override these global settings from your Details page of your Safeguard Desktop Player as shown in the example figure below:
Figure 4: Safeguard Desktop Player > Details page > Changing the encoding for individual audit trails
-
Telnet codec: To deal with special characters, you can set the default codec to display text. The SPS default settings for the Telnet codec is 500 and for the Telnet alternate codec is 310.
When you open an audit trail, the Safeguard Desktop Player application automatically validates it. You can see the results of this validation above the session details.

The following describes how to replay an unencrypted audit trail.
To replay an encrypted audit trail, see Replay encrypted audit trails.
Prerequisites:
The audit trail must be available on the computer running the Safeguard Desktop Player, or you must access it on the SPS search interface from a browser on the computer running the Safeguard Desktop Player. You can use the SPS Search page to download an audit trail.
To replay an unencrypted audit trail
-
Open an audit trail to replay. Use one of the following methods:
-
Start the Safeguard Desktop Player application from the menu or the command line, then click OPEN. Select the audit trail you want to replay.
-
Navigate to the audit trail file in a file explorer (for example, Windows Explorer), and double-click on it.
-
The Safeguard Desktop Player application displays the details of the sessions stored in the audit trail file. It automatically starts to prepare (render) the audit trail for replay. You can start replaying the audit trail while rendering is in progress, this is especially useful for long audit trails.
To start playing the audit trail, click the thumbnail at the top, on the left. If the audit trail contains more than one channels that can be replayed, select the channel to replay. Alternatively, click the icon next to the channel you want to replay.
-
The replay window opens.
You can use the following hotkeys to control the replay:
-
Play/Pause: SPACE
-
Jump to previous event: p
-
Jump to next event: n
-
Enable video scaling (Scale video): Ctrl+Z
-
Toggle fullscreen replay: f
-
Decrease replay speed: [
-
Increase replay speed: ]
-
Reset replay speed :=
-
Jump backward, short, medium, long: Shift + Left Arrow,Alt + Left Arrow,Ctrl + Left Arrow
-
Jump forward, short, medium, long: Shift + Right Arrow,Alt + Right Arrow,Ctrl + Right Arrow
-
Search in trail content: Ctrl + F
-
To configure the visibility of seeker indicators for events, click 
. The Configure seeker indicators panel pops up:
Use the sliders to toggle between displaying and not displaying seeker indicators for a particular event type. By default, all indicators are on.
TIP: Indicator colors represent the importance of events. The darker the color, the more important the event is. In decreasing order of importance, the colors are: dark blue > light blue > white. Classifying events this way is required so that when events overlap, there is a clear guideline as to which one of the overlapping events is shown on the seeker. It is always the more important event that will have its indicator displayed.
In the case of the white indicators, which stand for on-screen changes, the degree of transparency signifies the volume of the change that occurred as compared to the previous on-screen change. Small changes are partly transparent white, while bigger ones are fully opaque white.
