is this anything
http://sourceforge.net/projects/faac/ read this somewhere..sorry
faad plugin needs the qtdemux plugin to play mpeg4/aac audio files in totem, rhythmbox, etc..not sure what distro I was playing with at the time
cheers
Thanks! I finally got the machine to work on. Installed faac and faab2 and before that
locate qtdemux
/usr/lib/gstreamer-0.10/libgstqtdemux.la
/usr/lib/gstreamer-0.10/libgstqtdemux.so
showed those files were installed.
And totem still has no sound.

Starting it from the command line I get the same error messages as in my PC where is plays
mp4 files well w/o faac or faab2 installed. However, on my PC I have gnome-2.24.1 installed.
Anyhow, we just do with mplayer, my good woman is happy with it.

. Click on file in thunar and
mplayer comes up, f and one is in full screen in x y size I have set it.
