Posting the same reply in both threads, perhaps one of them can be closed?
A few weeks back all the missing Episodes from S4 appeared, very nice thankyou! Except now the whole of S4 is showing as expiring in 2 weeks, and S1-S3 still show no expiry date.
S4 also seems to play out using legacy-VOD, S1-S3 using the IP version - the geek in me wonders if this is S1-S3 being classed as "BoxSet" and S4 is somehow "CatchUp". Not that it makes much difference, I'm upto halfway through S2 and only picked up recording them in S5....
