Remove Read_only attribute in dvdrw

When use packet writing (INCD) to drag/drop files from a recordable dvd disc
to a rewritable disc. The “R” attribute is also copyed. Editing and saving the fils is not allowed. I have to save the modified file with another name using “Save as” or copy the files from the recordable disc to the HD, remove the R attribute then send to the rewritable disc. Is there a way to remove this R attribute in a rewritable disc?

Thank you!!
