TNA podcast: Overseas births, marriages and deaths: records in The National Archives

I've rather been neglecting TNA podcasts recently, not that there's been anything especially wrong with them.
The most recent talk, by Keith Mitchell, recorded in April looks at military and civilian registers kept by the British authorities, and by churches, consulates and other bodies abroad documenting vital events of British subjects.
While TNA holds a substantial number of them, in a variety of record collections, there is reference to holdings elsewhere and online resources.
As Mitchell states upfront, "it's a very confusing subject." Unfortunately without any of the visual aids used during the live presentation this talk is hard pressed to make it less so.
