Comment(by anonymous):

 Seems like there is misunderstanding here, I already did my homework and
 even submitted a patch to mythtv, Im 100% sure this is _NOT_ an user
 error.

 grep LATM *
 config.h:#define CONFIG_LIBFAAD_LATM_DECODER 1
 config.h:#define CONFIG_LATM_PARSER 1
 config.mak:CONFIG_LIBFAAD_LATM_DECODER=yes
 config.mak:CONFIG_LATM_PARSER=yes

 libfaad, libfaac and everything that is needed to support it is already
 enabled, my wild guess is that some builtin library you ship is outdated.

 I have the latest multimedia libraries installed as well current mythtv
 trunk
