MLBatBat app video aspect ratio?

[yanksno1]

Hi, I'm using the MLBatBat app with my Galaxy Tab S 8.4 and was wondering if it's possible to change the aspect ratio of the video. Right now it fills the entire screen (width & height), and I'd like to change it to 16x9 if I can. Looked through the settings and don't see anything, so I'm guessing not.
