Should I be able to delete?

[Burnman]

should I be able to delete individual files on DVD+RW or do you have delete them all at once? Its just I am having problems deleting individual files when I have burned them on using Nero I cannot delete them, I get the following error message:
Cannot remove folder AUDIO.TS files on this DVD drive are read only. You cannot copy or move files over to this drive.

Any ideas

Thanks

You can't remove invidual files on a dvdrw, you must reformat the entire disc and reburn.

only DVD format that allows such a thing is DVD-RAM

Actually, I think there are utilities that can "kind of" remove them. It will make them unusable, but it is not like you really removed them (i.e. you do not recapture the space on the disk they took up). Its like crossing a word out on a piece of paper. The word is still there, but when you read the sentence, you just ignore the crossed out portion.

But I am only like 60% sure of this.
