The BBC did a few of these programs a year or more ago, and in the case of the above it is a repeat, which is still well worth watching, especially about how people managed. Isn't there a continuation episode next week?.
Not sure if this particular program is on DVD, but many have been made available via this means.
On a personal note, I was give a collection in volume form 'The Great War - The Standard History of the All-Europe Conflict',that were published in 1915 and followed on from there, while the conflict progressed. Leaving my previous property, the whole collection was lost for some reason. Last year I visited the local Salvation Army charity shop and found two parts to that original volume. Treasures to behold and now to pass on to the future generation, after my departure.
