Ah, I was wondering about that in fact. My various encoders were indeed acting strangely when I was trying to produce the combination. > MPEG-4 AAC audio is conventionally served in an MPEG-4 container. You might be able to put it in an MPEG-2 container instead (to match MP3), but I am not sure that is a sensible or useful configuration. Kris, note that the MP4 contains aac. Are you sure you're not looking for that? Or are you simply looking for an MP3 file? Philippe
