Released as Doctor Who: The Collection – Season 23 in Region B. Released as Doctor Who – Colin Baker: Complete Season Two in Region A. Only available as part of the Revisitations 1 box set in Region 2. Available individually or in the box set in Region 4. Only available individually in Region 1.

There are also minor variations having to do with technical glitches that occurred in the Region 2 discs but were corrected in time for the Region 1 release ( The Caves of Androzani, Remembrance of the Daleks, Complete Series Two box set). The Region 2 discs released up to 2009 have also been dual coded with Region 4, so the two have been identical; this practice ceased for new releases in 2010. The only exceptions are Vengeance on Varos, which fixed an error on the Region 2 version in episode 2, and Remembrance of the Daleks, which used the NTSC master due to errors on the UK version and issues about music clearance.
