Your ability to play downloaded video files offline depends on two things:
1. The format of the video file (flv, mp4, mov, wmv, etc;)
2. The video player you have installed on your computer.
If you have trouble playing any video files, we recommend you either download a different format from those available. Additionally, we recommend* downloading and installing the VLC Video Player as it plays all popular video formats.
