My guess would be that the plugin initialization fails and
doesn't return, but rather causes some unexpected exit.

You could try adding a debug output after

  if (!PluginManager.InitializePlugins())
     return 2;

something like

  fprintf(stderr, "initialized\n");

in vdr.c. If you get the output even though you get that weird
exit value, we'll have to dig deeper into DVR itself. If you don't
get the output, the mp3 plugin's initialization might be causing
this.
