I don't understance the difference returned via regular youtube searches versus ones performed by the api.
Here's my example query: http://gdata.youtube.com/feeds/api/videos?q=Alien Moons the universe&max-results=25&v=2&duration=long
The first result on youtube's regular search is what I'm looking for (Alien Moons Documentary, 44:28 in length). The same video is in the results of the API query, but it's not in the same order-- it's like half way down the list of results.
Isn't the whole point that the API is supposed to allow easy access to regular searches? I even tried adding the &orderby=relevance tag, but it doesn't help.
