This review is from: Doctor Who: K9 Tales Box Set (Invisible Enemy/K9 and Co) [DVD] (DVD)
Purchased this item from Amazon 25/07/08, checked the disc and found no problem at the end of episode 3 of 'Invisible enemy' as reported by earlier users. It seems that the problem has been sorted and it is now safe to buy this series!
