Just wondering why this model has varying specs from one site to another in the net. One site (lg.com/id/.../home-theater/LG-dvd-home-theater-system-HT805PM) has a specs with hdmi, coax, optical, audio L/R and even a portable input. This would allow at least five other sources (bluray, tv, ipod, etc.) to be connected to the receiver and to me this is a great deal since this is more or less a complete package. The other sites says otherwise. Ano ba ang totoo?
