Yeah - If you look a little deeper into the TCPMP site, it turns out there are lots of versions of 0.66. 0.66a - the first, is the only one that can play AAC. All the rest have had support taken out because of copyright issues.
You can still get the 0.66a here :

although it might still be up download at the TCPMP site - I haven't checked.
