Hola.
I'm sorry I write in english, but I don't speak your language. I undestand just a bit what you are writing ...
I am from an italian group who found some secret menues on LG RH177 (and for all LG RH1XX series). By changing these menu you can add further features to your recorder (MPEG4 recording, DVD-RAM support, for example) and you really can transform your RH177 into a RH199, implementing all the function of this one.
Are you interested?
Can you give us cooperation sending your secret menu settings, to improve our knowledge about foreign recorders' secrete menues?
Let me know.
