Take a look at the attached DirectRT .csv input file; it should give you an idea how to allow for mulitiple key presses for a single video.
You need to program a modified compound screen type file (see here in the DirectRT manual for more information: http://www.empirisoft.com/directrt/h...nd_screens.htm). You have to play the video at the same time as defining the key press you want to allow.
However, you will need to explicitly define the number of key presses you want to possibly allow for a single video on the same row of the .csv input file. The attached example allows for up to four key presses before ending. If you want more keypresses, you would need to add them to that same row of the file.
