Disc Not Empty. AUDIO_Ts/VIDEO_Ts/SystemUpdate

[osiris]

This probably isn't an error specific to imgburn but I figured this was the most relevant place to ask.

 

I recently bought a pack of Verbatim DVD+R DL disc and tried to write a disc file on to it. To my surprise none of the disc are empty.'ve used Verbatim DVD+R DL disc before and never had this problem. I open the file explorer and there are 3 folders in them, AUDIO_TS, VIDEO_TS, and a $SystemUpdate folder. Why are these files on here? Am I able to use the disc for my intended purposes? Is there a way to set imageburn to write over these files? Is there a way to remove the folders and make the disc usable?

 

I thought I was buying blank disc, I hope there's a way to deal with this. These disc are expensive,

They look like used xbox360 discs to me. Where did you buy them from?! You can't erase or overwrite them, they are WORM discs.
