Glidos is the original file also .mkv?
mp4 and mkv are very similar, but not 100% the same. You might try repacking the file. This is a pretty fast process. If you want to google it, it's called remuxing, with the letter U.
The top answer here has a lot of great and easy to understand info.
MKV has, can have, metadata that doesn't exist in MP4. So the issue is most like there. Simply having one chapter spanning the whole video can cause issues, for example, or rotation/transpose, display ratio. It'll probably not even play in this case.
The video most likely is encoded with the width smushed like that so the decoder used by 3D TVs can decode it.
