[mdlug] k3b keeps appending to DVD-RW

[R Kannan]

Dr. Meijer,

Thanks for taking the time to help.

But I think you misunderstood my question. I was not talking about
adding or removing files from a DVD project.

I was trying to erase the contents of a DVD-RW by using "Tools->Format
DVD-RW". When I try that it says the following

Checking media
Found DVD-RW media
No need to format DVD-RW media more than once.
It may simply be overwritten

But when I go to burn the DVD, it adds the new files to the existing
files in the DVD-RW without 'overwriting' them. How do I make it
overwrite the DVD-RW.

TIA for your help.
