WRITE DESCRIPTION HERE
On archive.org if the video is flagged and you need to log in to get access to it, I believe that is preventing the download.

Site now displays

Item not available
The item is not available due to issues with the item's content.

Perhaps 403 was returned due to the content being removed?

Yes most items on the site work fine but this one has been flagged so is behind a wall where you have to log in to access it, I have logged in and tried to download but it won't work and I'm assuming the program can't get past the log in and was wondering if theres a way around this. sorry I'm not a programmer or anything.
