I am looking at the Pio 436XDE. I have downloaded the manual for it and can see that the multimedia receiver connects to the screen through two system cables which I presume will carry both video and audio. Now these system cables do not appear to be HDMI. Excuse the dumb question but if HDMI is the all singing all dancing mdedium for digital audio and sound which ensures no degradation of signal howcome the system cables are no HDMI and then have a seperate lead for other control functions perhaps. Am I missing something or is there a lower quality connection between the multimedia receiver and plasma. There seems no point having HDMI in if there is no HDMI out. Like I say I may not be understanding something Please help me understand?
