While in HDHomeRun View, press the Play/Pause button 5-10 times.

What you can do here:

• Change the UI in View. Online Beta will enable showing what show is next in the guide with a right press.
• Enable/Disable hardware encoding
• Transcode to H.264/AVC - When I changed this from "Mobile" to "Heavy" on my Shield, I saw an improvement in picture quality in both View and Live Channels.

edit: Trick is, the Shield remote doesn't have a Play/Pause button. I used a keyboard.
