While editing the item in your questionnaire, what are you putting in the 'File Name' field?
Here's what I'm inputting:
Code:C:\Program Files\VideoLan\VLC\vlc.exe -vvv "C:\Videos\ExampleVideo.mp4" --fullscreen --play-and-exit
It would seem that if you enter in the command line arguments within the same field, you'll be able to achieve the desired result.
I've attached a screenshot to further assist - hopefully it helps.
