I accept that for some assine reason on the main computer you tube videos will not show the video part,I will watch them on peoples blogs (MINE Included).but give up trying to watch videos on you tube. this non video displaying goes for both Fire Fox and Internet Explorer.I have tried to correct the problem but cannot.Therefore I accept that I am powerless over this.The frustrating part is that I CAN watch the videos on you You Tube on the back up computer using both the browsers that have been mentioned in this post GO FIGURE!
