If you can't play videos once you've successfully installed the YouTube for Mobile app, one of the following issues may be causing the problem:

• Your phone may not support streaming video. Check by trying to play a video at http://m.youtube.com
• Your streaming video access point may need to be configured outside of YouTube for Mobile. Depending on your phone and mobile data provider, this access point may need to be the same or different from YouTube's. For more help with these settings, please see the "Access Settings" article.
• If you've successfully played videos with YouTube for Mobile before, your network connection may not be strong enough at the moment. Please try again later.
• Your carrier might block RTSP traffic which is required to transfer the video.
  
  hope this helps
