Videos break out of the media container when viewed on small screens using the responsive template. The videos are responsive to a certain point, below which they stay at the same size. Media continues to resize vertically, but stays at the same size horizontally.

The example at fitvidsjs.com/ does not break out - this is the result I am looking for. Is this a template problem or a feature of AllVids?

Thanks!
