Before you ask any questions, do RTFM! 

Your mouse has a right button. Use it! Many features, like demuxing
audio, setting AAC-sources to be HE-AAC, setting default flags, are available
through the right mouse button.

recent important notes:
- use Open-DML, legacy-index and RIFF AVI size = 1 MB to avoid that Win XP hangs 
  when clicking on an AVI file
- HE-AAC is not detected automatically! Remember again: You have a right mouse button
- Video lacing is a severe hack and only there for testing purposes! Read the manual
  before using it!
- KISS divX players don't read AVI files with rec lists. The Aldi Medion player
  behaves the same way. And some players won't read Open-DML files!
- MKA splitting is broken!!!
- Low-overhead-mode for AVI files is not compatible with all AVI readers!


If you still intend do ask something, then read

With "read it", i mean "read it", not "just click on 'mail me'".
