I cannot close or finalize a multisession data disc with my pioneer 105 DVD burner. The close cd dialog box appears and then dissapears. I have tried nero (same result) and other software. In all DVD aspects the burner is superb. All software and firmware updates are current and I have even reformatted and reinstalled XP pro on one of my drives and then installed easy cd (on its own) to prove its not a software conflict. The problem cannot be in the write as I can take the disc to other comps in the house and close them with no problem. PLeeeeezzzzz help.
