Do you have a home theatre?

If so, can you help with some basic answers to a few questions?

We're moving into a new house next spring, I plan to have a 4K TV and 7.1 Surround in a home theatre in the basement, but want to have it pre wired. I want the TV to be against one end of the room, but the components such as the AV, DVR, Xbox & PS4 to be on the opposite side of the room.

Since the distance will be a little long, will an HDMI cable between the AV and TV still work? Or should I convert it to Cat5 ethernet? (Or Cat6?) Should I run 2 Ethernet cables instead of one?

From what I understand, Netflix will stream 4k content at about 15mb/s so a single Cat5 cable should do just fine, but someone told me that dual ethernet cables would be required, but I don't know why.

I'm also wondering about latency. If have to convert HDMI to Ethernet, there could be a delay in video which would push it slightly out of sync with the audio. Do modern AV units have an adjustment to tweak and fix this? (IE, can I delay the audio by a few milliseconds to fix the sync problem if there was one?)
