erasing dvd-rw

i just copied a game onto a dvdrw but it doesn't work, so how can i erase the data or rewrite over it to burn something else?

 

If you have Nero, go to Extras and click erase disk.
HW.

 

Some programs (e.g. Nero) would volunteer to erase the disc for you before it burns.

 

All burning programs will ask you if you want to overwrite the data on a RW disk when you go to write a disk. You don't have to erase it before hand, it will be writen over the next time you burn the disks.

 

anyway to do it for dvd decrypter (erase or rewrite)

 

like i said in my first post, it does it automatically. don't worry about it.
