After searching and posting on here, I find that my 2008 MacBook will support HDMI video-only and not sound. My MB works with my Panasonic HDTV through VGA ok and I will have to have a separate audio cable. Does it make much difference in picture quality? (HDMI vs. VGA). I need about 20' foot of video and audio cable to use in order to not move my MB from its Internet connection. (My tv is not wi-fi enabled.) Summary: HDMI cable plus separate audio cable? or VGA cable plus separate audio cable? or HDMI or VGA cable and use my existing external computer speakers for sound?
