Does the dvr/stb support ethernet over hdmi? I recently ordered some new hdmi cables for other reasons, but went ahead and got 1.4b... well high speed cables that support everything in the 1.4 spec is a better way to put it. I have my doubts, but was wondering if uverse supports this in their boxes? If not, are there any plans on doing so? Main reason I am asking is because my boxes could then supply ethernet though the hdmi for tv, ps3, etc without the need for additional rj-45 connections or using wirelesss.
