I just bought a Plextor DVD RW (PX-708A to be exact) and as I am a DVD n00b I have a question...when writing to a DVD +R medium, does the disc need to be closed much like CD Rs?

The drive came with Roxio 6, so I burnt a DVD with a lot of mp3's :D Then selected the option to "eject" it and checked the option to permanently close the DVD, thus not allowing any more content to be written.

Now the DVD won't be recognized as valid, it acts as if it's empty. Did I do something wrong?

Any ideas? :D

Won't be recognized in the plextor or your other DVD drive?

The Plextor. It's like I locked the DVD? For the others I burned I didn't select the option to close it.

I'm not sure, but did you check for an option in Roxio to close the DVD?

Yes, on the DVD that cannot be read anymore, I checked the option for Roxio to close it. Was that wrong?
