I haven't followed this as I just arrived on this list. But.

Normally if you were downloading from a video site you'd use youtube-dl, 
right?

Maybe I should be reading this thread online, but.

Normally "youtube-dl -F <link>" would show all the available formats.

Then "youtube-dl -f <number> <links>" would download a format specified 
by number as you got it from the previous command.

The URL specified in below message gives me a 403 error though 
(forbidden).

When you do -F the first list gives audio-only formats, the middle part 
gives video-only formats, and the remaining part gives both. Usually 
there will be something like "webm" and "mp4" in it.

Just some common knowledge here, like I said I haven't been able to read 
the rest yet.

Regards.
