A single-layer DVD+R or DVD-R will hold about 4. 7 gb. The more expensive dual-layer DVD+R and DVD-R formats can hold just over 8. 5 GB, though not all DVD-R and DVD+R drives can burn a dual-layer disc.
That depends on the dvd. Dual Layer dvd's hold 9. 4GB while DVD-5's hold 4. 7GB and DVD-10's hold 8. 75gb. Most packaging for dvd's list how much data can be stored on them or approximately how many hours of video may be burned to them.
