I downloaded the files as well. After zipping them together, it plays fine. Since it's a .mkv file, I use VLC media player. HTH.
I zipped them too, it was fine and then I have a player that reads mkv files, I already read an other video on it, but this one, instead of playing a video, it's like the pictures of this video.. I mean I don't know how to explain it but, anyway.. I'll deal with it!
