PlayUV is a command-line based tool. If it opens up a console window and then immediately closes it, then it means you didn't supply a command-line parameter to the application.
There are a few different way to use command lines. Here's one way to do it:
Open up start menu, click the search bar and enter "cmd" and press enter. cmd.exe (windows command prompt) should open. Then input as following, where <folder> is the folder playuv.exe and the TGQ file are in, and <filename> is the filename of the TGQ file.
Code:
start /b /d "<folder>" playuv -doublex <filename>.tgq
For example, assuming your tgq file is intro.tgq and playuv.exe are in your My Documents folder: (substitute <username> for your username in Windows)
Code:
start /b /d "C:\Users\<username>\My Documents\" playuv -doublex intro.tgq"
The video should then play.
