You could try to use the patched delfina.library from Smack. I'm using this one (patch2):
http://jpv.wmhost.com/delflib_patch_2.lzxI don't remember how big files I've tried to play, but I guess at least 100MB.. and all have played fine. I mostly use Amplifier and Delfmpeg.
Amplifier also streams nicely the mp3-streams..
I haven't tried betas from IC, but all newer Petsoff betas still had that hang bug with Lite (Smack's patches fix that).
