Like most folk, I imagine, I at first went bonkers on buying f**king DVDs and I now have about 50 or 60 of the bloody things, as well as about 20 that came as free gifts in Saturday newspaper supplements - which mostly I've not yet watched.
Now, I very rarely buy one, unless it's a classic fillum (The Third Man, 2001-A Space Odyssey) or an outstanding TV box set (Our Friends in The North, The Singing Detective - and soon Tutti Frutti).
