Philips DVP5140: Sub_style e SetMeg4SubtitleParamsO DVP5140 não é vendido no Brasil, mas faz parte dos meus testes porque tem caracterísiticas interessantes, não sendo igual a nenhum outro aparelho Philips que eu conheça. E quanto mais aparelhos distintos você analisar, mas fácil fica encontrar padrões.
Você poderá notar que o DVP5140 tem um código
muito parecido com o do DVP3040
