It actually works perfectly even on 3 hour or even 4 hour videos! I can see that many people have been having trouble recently, I see exactly what they were seeing. when I go onto a video and press download, the progress bar just disappears, being replaced by "reset". No matter how many times I tried to download, it wouldn't work. Then I reloaded and it worked fine every time :D. I don't know if this will work for everyone but i really hope that you all try. it.
