lost itunes media folder?

I tried to move my iTunes library onto an external hard drive to be able to access it there and make more space on my laptop. So I dragged and dropped my itunes library onto the external hard drive with no problem. Then I deleted the old itunes library on the laptop.

When I tried to open my library I could only see my Music but none of my TV shows and Movies. I tried to change the location of the itunes library as well in the advanced pane in preferences but couldn't get it to point to the iTunes library on my hard drive for some reason?? and then when I checked inside the iTunes folder I noticed that the iTunes Media folder was missing...

I resorted to moving the itunes library off the ExtHrdv and putting it back on my laptop with hopes that it would all magically work properly again but it's not. I still can't find see my movies and tv shows. The music is there but nothing else. I think my Media folder has disappeared? But not sure how that happened if I grabbed the whole itunes folder and moved it...the media folder was in the itunes library folder....

I feel i've really jumbled things, but know that my movies can always be downloaded. How do I fix this? How do I get my media folder back? Do I just re-download all the stuff that's missing. Will it be put into an invisible Media folder somewhere? And how do I move it all onto the external hard drive properly?

Thanks
