Need to backup a Blu-ray movie

[JCF2013]

I already have the movie extracted to my hard drive (don't know if that's the correct word to use). The folder is named THE DARK KNIGHT and it contains BDMV and Certificate folders. How do i burn it? do i just add the whole DARK KNIGHT folder or do i add each folder separately? check attachment to understand what i mean.

Both would produce the same result as ImgBurn should recognise you're trying to burn a bd video disc.

 

There's a guide for bd video burning in the guides forum.

I thought that was the problem because the first burn was a fail, an error showed up at 67%, something about ilegal request..etc, it was a cheapo disc i bought from a store for IT's, bad "strange" discs for movies. Tried with Verbatim and finished without problems. Thanks.
