As I own the box set of "It Ain't Half Hot Mum - Complete Series One to Four" and the individually sold Fifth, Sixth, Seventh and Eighth series, here is some information not provided at all or not provided correctly by Amazon in the item descriptions:
* The number of discs in the box set (Complete Series One to Four) is 5, not 4 as stated by Amazon. * The run time of the box set is 13 hours 47 minutes. * All eight series are for Region 2 AND Region 4, not just Region 2 as stated by Amazon. Region 4 covers potential buyers from Mexico, Central and South America, Caribbean, Australia, New Zealand, Oceania.
I hope that this additional information will be helpful and wish that Amazon was more careful in describing its products.
