Original.bin:   original firmware dated August 2006 for Metronic
                twin box evo II with terrestrial tuner NhPH1/3
Modificado.bin: firmware with the following improvements:

Improved handling of 16:9 video:
- when 16:9 option is selected in the settings menu the box
  will neither scale the picture nor add black side bars, instead
  it will switch the 16:9 signal on pin 8 of "TV" scart socket to
  allow the TV set to adjust the picture size. This way the full
  picture resolution is preserved and is the recommended setting
  as long as the TV set supports 16:9 switching through scart.
- when Letterbox option is selected the box will scale the
  picture to 16:9 size only when the transmission is 16:9, thus
  4:3 content will be properly displayed unscaled. Also the 16:9
  scaling proportion has been corrected.
- when another box connected into the "VCR" scart is turned on,
  the box will bypass the signal to the "TV" scart always
  signalling 4:3 mode. This corrects some compatibility problems
  since the hardware is not able to bypass the 16:9 switching
  signal.

Corrected some Spanish texts:
- examples: changed "Codificar!" to "Codificado!", "Lenguaje" to
  "Idioma", "Vista" to "Fin" (shows up at the end of a channel scan)
  "Un evento" to "Una vez", "instalar Inicio en Canales" to
  "indicar canal inicial".

Transponder lists updated:
- The transponder list for satellites Astra (19E), Hotbird (13E)
  and Hispasat (30W) has been updated on December 18 2011.

  The internal list has been updated so it will be preserved when
  the box is reset to factory defaults.
