Not sure if a totally agree with Cat6 requirement for running 1080P movies. For lengths shorter than (<100'), cat5e is sufficient for gigabit, and 1080p.

If using Ethernet to pull files from a NAS or file server to local playback devices - then you'll be using Gigabit ethernet (1 Gigabit/sec), and Cat 5E is more than enough. Encoded DVD files are only around 8 Megabit/sec, and Blu-Ray files are mostly between 20-40 Megabit/sec bit rates. Gigabit ethernet can handle several of each with no problem.

If you're going to do "video distribution" and push raw HDMI (uncompressed) over dedicated cables - that's more like 1-2 Gigabits/sec each, and then I'd suggest Cat6.


Talking of 1080P streaming, would most people actually notice the difference when playing a 20GB M2TS (Raw blu-ray file), as apposed to a compressed 4GB MP4 version of same blu-ray movie?

This would prevent your hard drives filling up 5x faster. Some would say wasted space even.

Good observation on the Cat 5e versus Cat 6 for video streaming, as I mentioned above, I hadn't verified that. It sounds like GbE is good enough for home video streaming. I think one of the points is to future-proof the house for applications that we haven't dreamed of yet. Maybe full 3-D holograms could be supported by 10GbE? Any other ideas? I'll certainly check in with my neighbor about this.

And in terms of being able to tell the difference between 20GB M2TS and 4GB MP4, well, that's a question for the videophiles. I (speaking for myself) would like to believe that I can see the difference...
