Comment(by Joern Koerner <joern.koerner@…>):

 Let the things clear up a little bit:
 The error itself ("NuppelDecoder: lzo_init() failed, aborting") is
 generated in libmythtv->nuppeldecoder.cpp at ~line 86. At this point the
 linked library "minilzo.cpp" is called. So the initialisation of the lzo
 lib failed.

 So far I found some interesting comment when I look at the minilzo sources
 (testmini.c)
 -- SNIP --------------------------
     if (lzo_init() != LZO_E_OK)
     {
         printf("internal error - lzo_init() failed !!!\n");
         printf("(this usually indicates a compiler bug - try
 recompiling\nwithout optimizations, and enable `-DLZO_DEBUG' for
 diagnostics)\n");
         return 3;
     }
 -- SNAP --------------------------

 Also the README of the mimilzo lib tells:
 ...
  If you are running on a very unusual architecture and lzo_init() fails
 then
  you should first recompile with `-DLZO_DEBUG' to see what causes the
 failure.
  The most probable case is something like `sizeof(char *) !=
 sizeof(long)'.
  After identifying the problem you can compile by adding some defines
  like `-DSIZEOF_CHAR_P=8' to your Makefile.

  The best solution is (of course) using Autoconf - if your project uses
  Autoconf anyway just add `-DMINILZO_HAVE_CONFIG_H' to your compiler
  flags when compiling minilzo.c. See the LZO distribution for an example
  how to set up configure.in.

 My configure parameters and it's output are:
 ./configure --prefix=/usr --enable-audio-oss --enable-audio-alsa
 --disable-audio-jack --disable-audio-pulse --disable-distcc --disable-
 ccache --enable-vdpau --enable-dvb --dvb-path=/usr/include --enable-x11
 --with-bindings=perl,python

 This is the same (well and correct) way mythtv tries to initialize the lzo
 library.
 I will try get more info.
