Dvd shrink to DVD

I am using DVDSHRINK to make a back-up of Shanghai Noon. However when it comes to copying it to DVD it claims that there is not enough space on the DVD+R.

In DVDSHRINK preferences I have it set as DVD5 - So it shouldn’t go over should it? When i try to burn the files created in Nero alone I get the same problem with Nero saying that:
Data to be written: 4483MB
Space available on disc: 4482

Any help appreciated. Thank you.

Try to save on HD output files in ISO format, and then use DVD Decrypter/ImgBurn or CD-DVD Speed to do the burning.
