Photo Journal MP4 Header: Desctop – OK, Android Mobile – Not working, iPad-OK bu

Hi Guys looked at your previous discussions nothing like mine:) Nice theme by the way, thank you developer! So, I'm creating my website www.ijigjig.net and using MP4 Header and Gif Background. Desktop version - it's all working well. Android Mobile Phone and Tablet - No header - black spot instead, but text of it is there. Gif Background Works. For Apple iPad otherwise - MP4 Header works well, but no GIF Background. Could you please help me fix it. I already asked my hosting provider they did their best of what they could but can't resolve without you and I'm sent here to ask support. Thank you! I hope it's something easy quick fix like plugin or something I don't know:) I hope you could help me fix it. Thank you! Alex
