The show was a huge hit for ITV on its original broadcast in 1971, and its team of writers included Bill Oddie, John Cleese, Graeme Garden, Graham Chapman and Jonathan Lynn.
One episode, written by John Cleese, featured a manic, ill-mannered hotelier; the prototype Basil Fawlty.
Doctor At Large starred Barry Evans and featured the likes of Arthur Lowe, Patricia Routledge, Hattie Jacques, Mollie Sugden, Maureen Lipman and Roy Kinnear.
The DVD set, with a running time of more than 12 hours, is released by Network on May 28, priced £29.99.
