Video iframes not resizing in Responsive Flexslider

I've got a Flexslider running on this page:
It's working rather well in Firefox on desktop, but in iphone, the iframes won't resize like they do on the demo. It may be my fumbling attempt to put a youtube video in the slider...Not sure.
Any help would be appreciated!

Instead of worrying about the frame resizing you should probably look at the design flaw
If I click play on the video then a few secs later the video is gone and next slide is shown - what is the point of that.
Why not have a static slide and open a lightboxed youtube video

From about 450px to 750ish there is no slider.  You should check your media queries to make you have accounted for all widths.

Check your site in chrome console or firebug.  

I saw for instance your vimeo code is not doing anything.

I think that has something to do with my wrangling Youtube into Flexslider when it originally supports Vimeo only. I added some API code for Youtube, but I think I didn't do it correctly.
It was working before and now it looks like I've fudged it up!
I think I will use the lightbox. It's classier...

It would not be counter intuitive that clicking a slider link would open in a new frame (lightbox)

I like the lightbox effect. I used it on another site with Advanced slider. Unfortunately, that slider didn't run a continuous carousel effect, and I'm too green at javascript to figure out how to make that happen.
With most lightbox effects all you need is to give the slide an ID and then initiate the plugin using that id

I added Fancybox for the videos and it works like a charm!
