Hi, how would you know if a projector has a 1.3 HDMI port? i currently have a panasonic DMP-BD30. Is it safe to say that if i can't play stutter free images on the projector using the said blu ray player, it means that the projector itself is not 1.3 HDMI? (note: Panasonic DMP-BD30 is HDMI 1.3) your help is greatly appreciated.
