Oh yeah. Movies/videos are definitely the most space-consuming of all media. Tons of pictures in their own rights. You said they're all in 1080p also? Yeah, that's a killer. Of course, you know this for sure (it IS your computer after all). Question is, how are you going to fix this? External HDD, new internal HDD, or delete a lot of stuff forever?
Also, off topic... If your computer is full off of your own things, I kinda wonder how much media a website like YouTube is filled with... Probably thousands of terabytes already. Wow. Sorry, off topic thought.

It hurts to think of the Youtube data usage...The co-founder of a fiber-optics company in my area came to my high school's career day, and it was a stretch to even start to comprehend the amount of data floating around, not to mention the bandwidth...Sorry, I'm off topic too. And babbling.
Oh man. You had to mention bandwidth... That is not a force to be reckoned with. Millions of users almost every 10 minutes would literally kill an average website. I don't even know how to guess the amount of data that's streamed every living minute of YouTube. The people of Google must get paid a lot.
