It's true. Is the same video http://www.sharemania.net/threads/katy-perry-this-is-how-we-do-palladia-1080i-hdtv.8358/
yes, before posting it, i searched a post with this file, but i didn't find something, so i made the post, but now that i saw that this file was captured by Angel, you can remove this post!
Because search doesn't work well. If you want accurately to find something, you should do it manually with helping Thread Display Options (Sort threads by Title). I always do it.
If you use the search function, do not add the "-" in the search string. I had no problem to find Angel's post. My search string: Katy Perry This Is How We Do Palladia and klick on "Search titles only"
