APLTablo is a Graphical Java client for use with the Tablo OTA DVR Appliance.  The graphical nature uses JavaFX.  This used to be included
with Java, but as of Java 11 is not, and that complicates its usage, but not impossible....so, first you'll need this tool (which you have because you are reading this)
then you need to have JavaFX, you could just try launching with the command

java -jar APLTablo.jar

If that doesn't work, you'll need to get a version of JavaFX.  A precompiled version for your OS can be downloaded from here

Download and extract your OS Specific version that is the appropriate for your Java, then from the command line issue the following command
from the APLTablo directory

java --module-path <place where you extracted it, we want the lib folder> --add-modules javafx.controls,javafx.fxml -jar APLTablo.jar
