This app is a real time saver.
Sometimes there are training videos out there that you need to go through, but they are really amateurish, with a guy reading from a teleprompt really slow to ensure that the dumbest people can keep up. Other times a good video is embedded in some Youtube player knock off that doesn't have playback speed controls or takes forever to reload when you need to skip ahead or go back a few seconds.

Enter VideoDownload Helper. You grab the files you need, you play them in whatever device, on board whatever flight or train and at the speed that you need. Streaming is great but sometimes grabbing the file is better. Kudos to these guys.
