Question 1

I'm seeing conflicting information. Does this allow me to view tv in HD?

Accepted Answer

What Angel T. and Miles O said is correct. With the EXTEND model you can receive HD video over an 802.11n (2007) or 802.11ac wireless connection. Your router's user guide or specification sheet should tell you which one  it is.

Note that as Miles indicated, it depends on what model you buy. The EXTEND model has a 'transcoder' that reduces the amount of bandwidth needed to distribute the video over your wireless network. As always, your wireless signal should be good. If it's not, you may experience quality issues.

Question 2

What is new in this 4th generation unit? I'm especially interested in knowing if the tuner is now more sensitive.

Accepted Answer

I have to wonder if the old blue single unit is more sensitive.  I wonder if having one antenna for 2 pictures involves a splitter than reduces each RF input by half.  You could probably get an old blue unit cheap on Ebay & compare its performance.

Question 3

How much hard drive space per hour of HD video does this require?

Accepted Answer

That depends on the movies, your cable provider, and the kind and amount of compression they use in delivering the movie to you. In my implementation I was able to store about 260 HD movies on a 2TB hard drive.
