Three questions:

I'm using Psytel Aacenc 2.15.
I tried: aacenc -production -br 256 -low_ath -pns

Why do the demos at http://www.psytel-research.co.yu/showcase.htm have a perfect constant bitrate, ie 192, 128? While my cbr aac files are 252, 251, ect. (aim is 256).

Why do they have the mp4 extension? Whats the difference?

Why do they use mp4_in.dll instead of aac_in.dll in Winamp (i think) and how do i make mine like those with psytel aacenc 2.15? (if i can)

I'm kind of new at this, thanks.
