Problem with Video Background

Hi! I have a problem in my website. Instead of showing me the video background, it shows "Your browser does not support the video tag.", and I'm sure my browser supports it. It worked for a bit, but then, after I did some changes on the website it stopped working. These were the changes:

1. I assigned the "Show featured articles" option to two item menus. This was a mistake, but whatever.
2. I activated Conservative Caché, GZip compression and disabled Sessions

When it started to fail, I reverted this changes, but it didn't work anyway.

Now, I don't know if it's the templates fault, the hosting company fault (They work with IIS) or mine, so I hope you can shed some light on the matter.

Thanks in advance.

That will show up when there is problem with all <source> tags within video tag. Iy they point to bad url or even you maybe removed them.

Well, I'm sure the videos are in the right place, because I didn't even change the ones that come with the template yet. I'm checking permissions just in case.

My Video Background component's html looks like this:

Is this normal? Where should I check if the <source> tag is correct?, because I can't find where you set the background, not in the joomla backend or in joomla's files.

EDIT: Website is this , sorry I didn't post that earlier.

Content of custom HTML module in header1 position is this:


So it seams you accidentally removed video tag along with tags in it

Thanks!!

Looks like TinyMC removed <video> tag and all within it each time I saved changes, even on HTML mode. I switched to codemirror, copied that code, and now it works.
