When you record videos directly to a Mini DVD using your camcorder, the disc is typically finalised when it runs out of storage space. This just means that no additional editing can be done to the contents of the disc, and the disc can be read in any computer. If you need to finalise a Mini DVD and you don't have your camcorder handy, you can perform the same task natively in the Windows operating system.
Insert your Mini DVD into your computer's DVD drive. Place the Mini DVD in the small circle designed for smaller CDs and DVDs in the centre of your DVD drive's disc tray.
Right-click on your Mini DVD's icon. Click "Close Session" to finalise your Mini DVD without using your camcorder.
