These days I noticed that Youtube API which I\'m using on my project is no longer available, e.g.
https://gdata.youtube.com/feeds/api/videos/dLEk9yiXVQs?v=2
If I'm understanding your question correctly then you should be using https://www.googleapis.com/youtube/v3/videos?id=<video_id>&key=<YOUR_API_KEY>&part=snippet
from now on.
Google shutdown the old API effective April 20th, 2015.
Take a look at the newest v3 API getting started.
You can use this link with your Youtube channel id after the = and it should work.
https://www.youtube.com/feeds/videos.xml?channel_id= your youtube channel id number
