Problem with DVD-Decrypter

Iam trying to copy a non-protected DvD+R DL Disc to a video_TS file so i can burn it with Img burn

BUt i got this error:

Does anyone know what i can do. Also does img burn/dvd decrypter automatically removes the Region code?

The disc seems liek tis damaged…like appearing weird on the other side…if i buy some tool to clean it will it work again. Btw doesnt work with dvd shrink either
