The latest DVD is a recording of D'Ooge's edition of URBIS ROMAE VIRI INLUSTRES.
Each DVD contains the files in mp3 format, so they can easily be imported to an mp3 player or ipod, or played directly on the computer.
I am currently recording Eutropius' 'Breviarium', which will be my first 'authentic' Latin audiobook, to be followed by Nepos, Curtius, and the text that is known as 'Cato', and then moving on to other Roman authors.
Adler, by first production, merits a re-record - however, the complete audio course, despite its flaws does an good job of introducing the student to Latin. There is no other course like it currently on the market. As Adler took me 2 years to produce, the re-recording will not come in the forseeable future.
