Throttled downloads by certain uploaders?

[MadameMalady]

Sorry for the odd description, i'm unsure how to word this issue;

video-downloader works awesome for everything i've thrown at it... untill I tried to grab the Disney XD Gravity Falls season one compilation list from youtube (not piracy, they uploaded it.)

well, it has been abt.. 15 hours, I went to bed and woke up, and it is still struggling to grab episode one.

maybe it's bc it's a list? maybe it's the uploader?
it's not my internet, bc my xbox one's downloads are working fine still, and not being throttled..
