How to extract unfinalized -dvd -rw contents to pc

I have a panasonic standalone dvd recorder es10

my pc dvd writer [fairly recent liteon] doen’t recognise anything on the disk unless I browse to it with isobuster and then it shows one large track which I extract, but right on what should be completion of extraction it throws up a write protection error and deosn’t complete the extraction

Is there anything else I can use I want to reauthor the dvd’s contents and then burn to dvd -r

thankyou

Why don’t you close it (finalize)? If it’s a -RW you can erase it after.

Thanks for your asistance, all o’k now.
