DVD-10 discs are double-sided, single-layer DVD-Video discs and are sometimes referred to as ‘flippers’ since they need to be turned over to access the content on the second side. The DVD-10 format is much less common than DVD-9 (single-sided, double-layered discs) but were used more in the early days of DVD-Video, before dual-layer disc production was widely supported. DVD-10 has a storage capacity for video of 9.4 GB (4.7 GB per side). Single-sided, dual-layer discs (DVD-9s) were a feature of the DVD standard from the start, but some early players did have problems with them or needed a firmware upgrade.
DVD-10s don’t feature any artwork on the disc apart from a small area near the spindle hole to indicate which side is which. This is a criticism of the format, along with the difficulty of avoiding finger marks and scratches on the playing surfaces of the disc.
Some DVD-10s contained the movie on one side and bonus material on the other, or a widescreen version on one side and a fullscreen version on the other but some discs did split the film into two parts so the disc needed to be turned during the film, rather like a LaserDisc. Some people reserve the term ‘flipper’ for DVD-10s where the main feature is split over the two sides.
It is possible to find double-sided, dual-layer DVDs (DVD-18s), but these are uncommon, and reportedly more liable to playback problems.
