Orange, I'm new on this forum and this is my first post. I will tell you what I know.
I have not hacked my DMS (yet) and have been using AAC files (90% of my music is AAC) for 4 years now. I bought the AAC plugin from PhatNoise after getting my PhatBox, it was about a $10 upgrade. It always worked perfectly. Then about a year ago I put a new hard drive in my laptop and had to reinstall PMM, and there was a problem with the AAC plugin; as I recall it wouldn't take the activation code. I sent an email to to Phatnoise support and here is the response I got:

We sincerely apologize for the problem you encountered. We are experiencing technical difficulties that are causing problems with the PMM Plus Activation server.
Please go to

Download the file named PMM_3.92_FULL.exe and install it OVER your current installation. (You can right click the file, click Copy, then go to your desktop, right-click and click Paste.) Double click the file to install the full latest version. You should no longer need an activation code. We sincerely apologize for the inconvenience.

That worked for me. I have had no problems with AAC since, although I do have 1 or 2 songs that the PhatBox calls "Corrupt file" for some reason. But it's really only 1 or 2 out of 4000 songes.
All my files are m4a extension. I'm checking and I don't see ANY with aac extension. I have used several encoders (PhatNoise, ITunes, and NeroAAC) and the PhatBox has played them all with no problem. (IPod can play them all too, but my Creative Zen player had problems with Nero and PhatNoise encoded files. I found a hack online to fix them. It had something to do with file length, and NeroAAC has a recent release that fixes their problem. This is probably not relevant to the Phatbox but I'm just throwing out everything I know.)
So I'm not sure it was the file extension that fixed your problem.
Enjoy good music in your car!
