Short answer : No.
The iTMS DRM is only supported in iTunes 4 and up. Sorry.
I mean, that is, I'm not personally sorry, it's not my fault, it's just I feel bad about the whole thing, and I thought I could express myself by saying "sorry". In retrospect that was a bad move, seeing as how it was misleading with regards to my culpability in this whole affair of your not being able to burn your music. I'm sorry for that part, because that was my fault. So that clears that up.
Ahem.
