From time to time you will find that a video you have uploaded onto YouTube will not play on your mobile devices or TV. This can be due to incorrect setting of syndication rights on the uploaded video.
Follow the link to four slides which will tell you how to correct your settings on YouTube.
Take note that in some instances the YouTube rules controlling the use of third party material may prevent you from changing the syndication settings and you simply are not allowed to view the video on a mobile device.
