you are confused with the terminology. If you burn DATA files, mpg, .mov etc to a DVD blank so it can be played by any computer NOT a DVD player, the it must be finalised, which closes the data stream, and writes a proper ending, preventing it being over recorded. If using the computer menu system the finalisation process fails you probably set up the burning process wrongly. You usually get the option to burn the disk as data that you can build up, but by bit, remove the DVD, but still use it and add more – then you can finalise it – finishing it for good, or sometimes you get the option of doing different things. Jeff mentions authoring software – this using the .vob files get created in the software, and the structure is the same as a commercial DVD, with a simple or complex menu system.
When you say you can’t finalise it – we don’t know what kind of finalise you mean, or how you’ve done it.
Let us have the process – what did you do, what kind of blank is it – or + in particular, and when it won’t do it, what comes up on the screen. It’s possible you are trying to write to a disk that is the wrong type for what you want to do? My Mac also doesn’t seem to like some of the blanks I use on the PCs – it can read them, but writing to them falls over, and I cannot finalise a DVD recorded on the PC.
