Forgot to Finalize Disk

well nero 8 contais a finalize utility you can use to finalize it.

antoer method is to retrieve the data via certin software and then bur it back off one such program is CD RECOVERY TOOL BOX (dont worry it does dvd's as well) http://www.recoverytoolbox.com/cd.html

although its for damaged and unreadible disc it will retrieve the video from unfinalized disc as well.. I used it many taimes and it works perfectly
