A really stupid question: how to erase a DVD+RW disc?

[gb14820]

I am new at video editing, and am using a DVD+RW to try out my first few projects--I don't want to end up with a lot of coasters.

I've gotten a project to finally work out, and want to try something else. But Sonic DVDit requires a "blank" disc.

How can I erase my current project off the disk?

Thanks

Just open a burning program and somewhere there will be erase media.
for example, in nero under one of the upper menu's, there is a option that says erase media. most programs will give you the option to erase the media write before you burn to it.
