AirPlay from MacBook to Apple TV through Airport Express is choppy

So, I have

• Airport Express (A1392)


• Apple TV (A1427) connected to Airport Express via Ethernet


• MacBook Pro (13, L2012, 10.10.1) connected to Airport Express via Wi-Fi

Streaming video directly from Internet or from iPhone is ok, bit when I mirroring screen from MacBook to Apple TV, I get choppy video. Can I fix it somehow?
