As Diana pointed out, the network is just fine. Gigabit ethernet is super cheap, wireless supporting hundreds of megabits is reasonably priced (though harder for a home user to install properly so not a very good solution for streaming video, be it HEVC or MPEG4 encoded) and MoCA's 170 Mbps top rate has plenty of headroom. Directv can always update to MoCA 2.0, which doubles the bandwidth and makes up for the doubling imposed by HEVC. HEVC encoding is totally irrelevant to what you were responding to. Encoding happens at Directv (or before they receive the content) not in the customer's home. It is totally irrelevant to RVU.
