Yes. While you are playing a clip, you can use the up and
down navigation keys to surf to a different channel.
A small pop-up screen will be displayed that tells you

channels that you have access to. Use the navigation
keys to scroll through the different channels. Once you
find a channel that you want to watch, scroll to it and
press
(or simply wait approximately three seconds),
and the channel will begin loading.
