Actually, scratsh that. I was confusing these with the text only commentaries done for the prequels. I did some researshing and as far as I’m able to tell Pablo only did audio commentaries for episodes IV and V. If I’m wrong pleace let me know but I’m pretty sure that’s the case.
Also I’m not convinced these were realeased in 2004. Pablo talks abut episode III was if it’s allready been released. I’m guessing these came out in 2005.
