This page uses flashplayer to display the video, so this is a Shumway issue, not an html5 one. Can you still reproduce on more recent versions of Firefox? (32 is 3 months old now - maybe try current beta ( https://beta.mozilla.org/ ))

Surprisingly VK now delivers videos in the MP4 format too. The example has http://cs540205v4.vk.me/u40371781/videos/5ccefb8a33.240.mp4 . But download speed is so bad that visitors won't see progress in the progress bar and therefore will assume a failure. After waiting some minutes I was able to see some seconds of the HTML5 video. OP has the Shumway plugin.

This bug does not need to block Shumway's 1.0 milestone for ads.
