Doctor Who and The Silurians - VHS, CD and DVD Releases

VHS, CD and DVD Releases

The original 625-line PAL videotapes of the serial were wiped by the BBC for reuse, although they retained 16mm b/w film recordings. In 1993, the colour signal from a 525-line NTSC version of all seven episodes (except for part of the beginning of episode four) was used, along with traditional colourisation techniques, to colourise the film prints for the VHS release, which was in July of that year. In October 2006, the story's original soundtrack was released on CD as part of the 'Monsters on Earth' tin set, again alongside The Sea Devils and Warriors of the Deep, with linking narration from Caroline John. The CD was then individually re-issued in January 2008.

On January 14, 2008, a fresh restoration of the story (the black and white prints and off-air colour recordings were combined, with the colour prints distorted to reduce fringing and both prints VID-FIRED'd to restore video sections to 50 unique fields a second, rather than 25 frames a second with no motion information between the two fields corresponding to each frame) was released on DVD as part of boxed set called "Beneath the Surface" with The Sea Devils and Warriors of the Deep.
