mpg files do not playback

[studiomejia]

Sorry if this question was already posted, but I was not able to find and answer.
I batch uploaded some mpg files with their thumb_
They display fine on my gallery but I cannot playback those videos. Am I missing something?
Thanks

Works for me, ensure you have a browser plugin that can play these videos installed.
