Taking into consideration the error which popped in #39 should the app check every time it starts whether a video is downloaded partially or is corrupted?

More specifically I mean that if, for example, the computer loses connectivity with the internet when downloading a video it should delete it and start over again, to exclude any chance the video is corrupted. This example could also apply in a sudden reboot or loss of power.

I haven't reviewed the script that checks for the downloaded videos in depth, so if this has been taken care already just close/delete this issue.
