 First of all I´l like to thank Dwi Sasongko Supriyadi, Dwita loveme and klaus
 for the e-mails. Thank a Lot guys...

 The Good News

 I made progress, specially using the Makefile tip from Dwi and now my Asterisk
 don´t restart anymore, just the call. Here my full log when I try to execute the
 mp4play application. I´m using X-Lite 3.0.

 VERBOSE[7422] logger.c: --- (11 headers 0 lines) ---

  Any tip envolving that ?

  The Bad News   

  After did the command ldconfig, some error associated with the libgcc_s.so.1
  library isn´t allow me do nothing, like start Asterisk or even use yum:

 [root at telipplus001 ~]# yum list
 There was a problem importing one of the Python modules
 required to run yum. The error leading to this problem was:

    /lib/libgcc_s.so.1: file too short

 Please install a package which provides this module, or
 verify that the module is installed correctly.

 It's possible that the above module doesn't match the
 current version of Python, which is:
 2.4.3 (#1, Mar 14 2007, 18:51:08)
 [GCC 4.1.1 20070105 (Red Hat 4.1.1-52)]

 Tonight I will reinstall my Centos 5.x and Asterisk and I will try again ....

 Anyway, thanks a lot to all....

I had similar problem: there was app_mp4.so but Asterisk did not loaded 
it because there were missing symbols. I only had to execute ldconfig 
and restarting asterisk - then it worked.
