In the title list I sometimes get what appears to be a code after the title. At the moment I have '51' following one title, and 'S/W' following another. So it's "Film : Sphere 51" and "Casualty S/W". They do not always appear, in fact they are more often than not not there, but there have been others, details of which I cannot remember. Can anyone tell me what they mean? Are they significant? I have been unable to find any mention of them in the handbook. I am confident that as usual, one of you will have the answer. Thanks in advance once again.
