According to tvshowsondvd.com, several Netflix customers noted that their rented copies of Doctor Who: The Complete Second Series disc one had a problem.
Apparently at the 32-minute mark of New Earth the episode switches to a rather gruesome scene from "The Texas Chainsaw Massacre: The Beginning". Along the same lines, the special features section of the disc does not work.
Once the BBC were contacted and made aware of the issue they quickly responded with a statement that yes, there was a problem with the discs in question.
Only Netflix copies of disc one were affected and not those for purchase in stores. While the BBC works on replacing the faulty DVDs, Nexflix has pulled disc one as being available for rent until the situation is resolved.
UPDATE: The Sun picked up on this story in its January 26 edition, claiming it was an exclusive.
Headlined "The Tardis Chainsaw Massacre", it has a mocked-up picture of a Dalek armed with a chainsaw and quotes a BBC insider as saying: "It's very, very embarrassing. Doctor Who's a family show and the most scary thing is probably a Dalek, yet the Texas Chainsaw Massacre films are among the most frightening ever made."
A BBC spokeswoman is quoted as blaming a "manufacturing problem" and says: "We apologise for any distress we may have caused. We are doing our best to rectify this problem."
