Hello everybody here that makes walkthroughs and posts them onto YouTube so others can watch! There have been these people that have that have been filing false copyright on videos that they do not own whatsoever...
These companies include but are not limited to:
X Media Digital
These companies may have done this to your videos. All you have to is just dispute this. This recently happened on one of my Battlefield 3 videos and it takes away my over 15 minute allowed mark, so it dicked me pretty well! But for more info, here is a video that can help.
