Please check the following shows in this set and see if the running times match. Let me know.
Season 4 episode - To the Death
43m 17s cut down to 43m 12s for Cert 15.
Violence, probably neck snapping of Jem'Hadar, Starfleet etc edited.
Season 6 episode - Sons and Daughters
43m 39s cut down to 43m 4s for Cert PG.
Knife violence between Alexander and other Klingons edited.
Checked DVD slim-lines and the times are a few seconds shorter than that, but put that down to BBFC staff originally stopping their clocks late. But whatever accounts for it, clearly cuts were made for us.
Got the DS9 series already but worth considering if things are different now. There's always importing I suppose, but then you lose additional extras included as part of the R2 ones, but only on so-called "Best Buy" discs in R1.
Would also be interested in hearing if there is a 49th disc? By my calculation there's only 48. Is there a bonus disc with extras unique to this set?
