error erasing RW discs

[getgl]

I have been burning DVD+ and DVD- discs without a problem. However, when I have an RW DVD, the program freezes after reaching 100% erase and the bottom left corner message stays frozen in "erasing" indefinitely until I have crash out of it. Is this a bug or something that anyone has a suggestion about. It's Philips+RW DVDs. I am using Philips dvd+ and - without trouble.
