I have a Colby Kyros MID1042 tablet. I have downloaded every player I could get. I can get on youtube but when I click on a video it shows the picture with the play arrow in the center.but when I click on it the picture goes blank, and the runner at the bottom of the picture is run all the way across as if I had already watched it. The same thing happens to all videos. Any thoughts would be helpful. Thanks Gary.
