What is a DVD-R or DVD-RW drive?
DVD-R was the original recordable DVD format. It supports recording but not rewriting. DVD-R is supported by more than 90% of all DVD devices. DVD-RW is also a recordable DVD format, however it is also rewriteable or allowed to burn copies Blank DVD-RW and DVD-R disc formats can record up to 4.37 GB on a single sided DVD and 8.75 on a double sided DVD. The maximum writing speed of DVD-R recorders is 4x (5,540 KB/s). DVD-RW are written to at 2x (2,770 KB/s). This storage medium is great for storing movies. DVD-R is generally the least expensive media on the market today and it can be purchased for as little at $0.30 to $0.40 per DVD. Commercial movies are typically recorded on a dual layered DVD which stores up to 9.4GB, while DVD-R and DVD-RW only store 4.37 GB. There is however software that will shrink movies to fit on a single DVD-R and DVD-RM disk, one such software is DBD Shrink. DVD Shrink will remove content or reduce the quality of the movie to allow it to fit on a single 4.37
