When viewing a Viper Video YouTube embed on an iOS device, it just shows an image that is linked (that is sized wrong - not the sizes set on the settings page). Yet if I do a YouTube oEmbed it works fine.
See here for example:

It works fine on a computer, but on iOS you get the image link.

Bumping this. Viper my company is happy to pay you to fix this.
Please consider contacting the author directly (that's generic advice BTW, I've no idea if the author is interested or not in that) or posting to http://jobs.wordpress.net/ instead.
