A cat 5 would probably work fine, but does it impair and reduce quality of the audio and video being streamed? What a cat 6E work better? And longer-term I guess it would be better.
We know the video Signal may be fine, but the audio signal which has always been compressed in the past is now receiving more attention toward being uncompressed and with this would a cat 5 not work as well since many of us Herein are using a very revealing soundsystem when watching movies.
