I downloaded a video on my Playbook, and when I hit open file file it said: the file type is unsupported. When I plugged it in to the computer into the computer it WORKED.The question I'm asking is why the video is not working? By the way it's a MP4 file.
If you use Google Chrome or Mozzila Firefox, get the Youtube download add-on, download the video in MP4 1080p HD (For best result) and then copy it onto the BBPB.
