HOH on CD?

Anyone know if there is a version of HOH, or any decent poker books, on CD? I really need to understand pot odds better, but I don't retain written word as well as spoken. Plus, I'm on the road usually for 2 - 4 hours a day which would be prime for listening to a book. I have the HOH1 book, I just don't have much (still) time to read it. Anyone have any pointers on how to quickly figure out POs?

I dunno if poker is popular enough to commercially make HOH worthwhile in audio.

1) take some DVDs and strip the audio?

2) there are places that have volunteers that record books in audio for the blind; maybe if you make a donation they will record something for you?

Amazon has a very limited selection of poker audio books, but not Harrington. Maybe be worth a little googling.

but I haven't bought it yet
