Video Importer

I tried and tested a couple of YouTube video import plugins and none of them actually worked and none of them did what I wanted it to do. Which is just importing YouTube videos as they get published into specified categories.

Except for this plugin. This plugin did exactly what I wanted it to do and it works great!

So well done to you! 

Great plugin that actually works
