DVD-5 is an acronym that means a DVD disc that is one-sided single-layer disc
and can contain upto 4.38 gigabytes of data on it.
DVD-9 can hold approximately 7.95 gigabytes of data, even though marketers like to use the 8.5GB value instead, but this is misleading and is calculated by using so-called "Japanese gigabytes" which means that gigabyte is calculated as 1,000 megabytes, but in real computer terminology, gigabyte is 1,024 megabytes.
DVD-10 means a two-sided DVD disc that hold single data layer on both sides.

In essense it does not read DVD-/+R disks so a newer drive is the only option unless an updated firmaware has been written to include these which is unlikely.
