Which probably means the illustrations from Latin ABC were not so accurate we'd like them to be...

I have to admit being heavily biased on this issue. I believe that the dynamic nature of languages, and the inevitability of regional accents forming, makes "knowing" how Classical Latin was pronounced almost impossible. I would however be very interested to see some of these illustrated pronunciation guides you referred to. Whether Polish Latin is any more valid than English Latin is probably a whole nuvver question. I did smile at your statement that you would never pronounce "v" as "w" - to an Anglophones ears, Central Europeans don't pronounce "w" as "w", let alone "v."
As an aside, there's an interesting passage in one of Anne Mccaffrey's Pern series in which the loremasters are confronted with recordings of their language from millennia ago - entertaining and apposite to this thread.
