Youtube json feed returning all results

I am currently calling a youtube playlist using:

http://gdata.youtube.com/feeds/api/videos?q=USERNAME&v=2&alt=jsonc&callback=function

I was just wondering if there was a way to pull through all of the videos on my feed, I hav开发者_StackOverflow社区e around 250 videos and its only returning 25... :-/

Any help would be much appreciated...thanks!

25 is the default number of items that are returned. Use max-results=nn to request up to 50 items.
