How to re-use DVD-RW?

[walter4h]

Hi, guys:
On Jul 08, 2003 there was a post by Burnman "Should I be able to delete?"
(You can find it if you do a search for "reformat DVD-RW")
The problem concerned reusing a DVD-RW, which had some previously burned files on it. The answer was that you cannot delete the individual files, you have to reformat and reburn the entire DVD.
I have the same problem. But it is not clear what exactly should I do?
I use ReelDVD to author and DVD Architect to burn.
Reel needs smth in the storyboard area, I am not sure it would allow me to go through the authoring process with no assets imported.
Can anyone please advise about the details of reformatting DVD-RW using these apps (or some other ones)?
Thx: walter
PS I want to thank everybody who replied to my post "Creating a single pic from video stream" in the Authoring section. I did not put a thank-you note there, as it would bump the post with no new input.

Look for the Erase function.
