Video not looping, or sometimes looping

Hi, I've added the YouTube video in a module on this page:
www.tiffanysmaleny.com.au/test

It is set as follows:
- one video set to autoplay, mute and loop YES
- jQuery NO
- noConflict YES

In Chrome it seems to loop once, ie. it autoplays on load, then plays through one more time.
In Firefox it didn't loop at all.

Are there other settings I need to check?
Thanks for your time.

Hi, thank you for looking into this with me.
I've updated the post with admin details.

I've experimented by repeating the video 5 times, and in Firefox it's looping beautifully, but Chrome and Safari are not.
I don't feel like I can trust it will have consistent behaviour in the multitude of browsers and devices that exist, so I'm not confident this is going to be the right solution.

If there's a setting I've missed, or something I can do in the template to apply to this module to ensure it will loop I'm happy to make those changes.

Thank you for your time on this, and any suggestions are welcome.
Carly
