A:AnswerI connectted to my antenna without a converter box. I don't believe there is an inbuilt antenna, you have to purchase it. You don't need a converter with this tv.
A:AnswerI don't have any way to measure it for you, but I can tell you that I wanted my old school DVD player, ( very thin, but old school by means of it's A/V cables,) and it won't fit under the TV. I would say it's about 2" tall.
A:AnswerI would reccommend that you get a Roku device and download the Xfinity App Beta version. You will love to roku and won’t have to pay Comcast an extra 5.99 per month for their little box. Plus is you have a DVR as your main box you can record shows and watch and replay them on your Xfinity App on Roku.
A:AnswerNo. You have to use the volume control on the Toshiba hand held, or on your cable TV provider hand held (after you program it to take over the functions of the Toshiba control box).
