Having hard time here!

I am having hard time to upload videos for my post. Gosh! The video shows when its just a preview but then when i publish it, it won't come out. You can see it in my post below. Hay...i almost give up. lol. I was thinking "i shouldn't grab it" but too late for me i already submit my url. If there is any way i could return it back from opps section i think would do that instead of me trying to work for it but still don't act right. It's aggravating you know..

Somebody know how please give me some tips...wahahah!
