Since there is no HDMI port what's the next best option to connect with, my TV is newer Panasonic big screen with all the ports. Is there a way to use only one cable to get both audio and video?
I don't believe you can use one cable for both audio and video.
If you've got a TV with an HDMI port, I'd use the mini displayport->HDMI adapter. You can then run a toslink cable from the pro into the tv (assuming the TV has digital audio inputs).
