I'm seriously considering the Olevia 747i HDTV. It has two built-in tuners and digital audio out. Does this mean that if I use a over-the-air (OTA) antenna to pull in digital & HDTV broadcasts that it will be in surround, if the original broadcast is in surround (e.g the next season of 24)?

Also, this TV has both optical and coax digital out. What is the distance each of these will carry the audio signal w/o a repeater? Which one will go further?

Finally, the TV has removable speakers. Does anyone know if they have standard binding posts / clips or do they have some type of proprietary connector?
