VCRPLUS Huffman code

Has anyone worked out the VCRPLUS code? The TVGuide has a litsing which can be used to set up a VCR by employing a series of numbers which encode date/timestart/timefinish/channel in a minimized sequence which I believe is a Huffman code(David Huffman-MIT MS thesis 1954) I am interested in if anyone has taken the time to figure out the algorithm? please respond to me directly so as not to clutter the list if you don't mind.
