Sorry it's taken *so* long to get back to you all, but I've just moved house and have only just got back on the net.
I spent about 30 mins tonight, looking at the BBC Treasure Hunt site and finding which shows I have that are apparently 'missing'.
I've listed the name, the tx date and the length of the recording I have. Some seem abnormally short so they may be extracts. Also, some have background noise like people coughing and computer sound effects (i.e. the ones Windows makes when it performs different functions) so Lord knows the route these recordings have passed through.
