Three *very* different versions of The Silurians:
1. UK Gold omnibus, March 1993 - unrestored 16mm B&W film recording
2. BBC VHS release, July 1993 - unrestored 16mm B&W film recording combined with colour signal from 525-line NTSC domestic recording
3. BBC DVD, August 2008 - fresh restoration, distorted to reduce fringing and VidFIRE applied to studio scenes
#DoctorWho and this footage belongs to the BBC. The clips are used for the purpose of comparison and therefore the video is intended for educational purposes only, no profit is gained from it. If it entertains, that's a bonus.
