It can't download video from vk.com. I have confirmed that it reproduces with several another URLs. Maybe with any video URL from vk.com.

BTW, direct video URL could be retrieved like this:

$ curl -s 'http://vk.com/video_ext.php?gid=5&oid=-69328224&id=456239594&hash=a25a3ac6971ed9bc' | grep -o 'http://.*720\.mp4'
