It is currently 1:06am and I am having problems watching the videos that are installed on my computer. After I press the play button, the video will play for a little bit but then stop and the bar that says how far along the video is will be at the end, but the video hasn't reached the end yet. Then I'll TRY to skip ahead and it will freez. All I want to do is look at my GoPro FOOTAGE! Is it windows 10 or my computer? Is there a way to fix it? I have had this issue with videos that were created with video recorders that glitched out when recording due to low battery when recording. Is it just one video or all videos. Also have these videos ever played correctly and all of a SUDDEN it affects all videos including past videos that use to play fine.

With my own issue like this I found that it was only the videos on the SD Card in the recording device that GOT messed up. All prior videos that were downloaded to the the hard drive of the system ran fine. I ended up reformatting the SD Card and making sure I had a full battery when recording and the problem went away.

You can try using a video player other than the one that comes with windows if its affecting all old and new. I use VLC Player which is free. http://www.videolan.org/vlc/index.html
