Another TNA podcast: British soldiers in India 1750-1914

Earlier this month I wrote about plans to podcast lectures given at The National Archives. TNA has since announced the availability of another lecture: Sahib, the British Soldier in India 1750-1914, by Richard Holmes, Professor of Military and Security Studies at Cranfield University. (See his BBC biography.) I still can't find any explanation of how to find these lectures other than by chance and perseverance. The two I've found so far are both in the directory www.nationalarchives.gov.uk/podcast/, but looking there directly just results in The directory you are trying to access does not allow the contents to be listed. Not helpful.
