The DVDs came out in 2005 (ironically between red sets 20 1nd 21 of the Classic series) and again in 2010. Both are now out of print, but being only a disc set (4 for the reissue) you may find a copy on Amazon US or UK from a Marketplace Seller (make sure you buy the right region, unlike the Classic series, Revival's discs are NOT region free) or from an ebay seller. Be very careful who you choose as your seller though.
