You are using the iPad, right???? And you installed the Skyfire app for the iPad?????
On the Skyfire's browser, under the address bar, there are six icons. The far right one, it looks like a cog wheel, this is the settings button. Make sure the "load page" is set to iPad. You can also open the see more settings and there is a FAQ link which helped me figure out my errors I was making.
ETA:
Depending on your network provider and your download speeds, Skyfire may not be able to buffer the streaming video fast enough to convert it. Just a thought.
