The point vidoman was trying to make above about packet-writing software is that there appear to be some pieces of packet-writing software out there which conflict with Video Studio in terms of controlling the DVD burner. (Basically, packet-writing software is for when you drag and drop files [i.e. packets of information] onto the burner drive and the files are written [i.e. burned] to disc. Windows XP provides its own, for instance, though a lot of people don't seem to realise it is there. But you can right click on a file and amongst the long list of things you can do, there is a 'Send to' message, and you can send it to your burner drive. You then get a message asking whether you want to burn it to disc, and you can either do so or wait till you have built up more files to burn. But even if you do burn, the burning process is such that the disc is left open for burning future files until its storage limit is reached.)
One of the programs I have had problems with in this regard is Nero's InCD. I had to physically uninstall the program to disable it as it does not allow internal disabling, unlike some other similar programs. But the conflict arose similarly to the problem you are now experiencing -- well into the burning process and just before the actual burning was to take place. Verrrry frustrating. But once I uninstalled InCD, and never let it or a similar program, back on my computer, the problem simply went away, never to return!
