I have been using windows 8.1 and when I would watch my recorded videos there was no problem. I had uploaded all my videos to my computer plus ones I recorded with the computer. I have not had any problem until I downloaded the new windows 10. Now when I go into my videos some will not play at all and others only show a black screen, but play sound. I did a driver update, but it did not help. I just want to see the videos of my children. I would like to transfer them to a disk but if there is a problem I do not trust that they will transfer properly. Why did my computer stop playing my videos after this upgrade?
