Pluto TV App Issue

On Pluto TV app, some shows stream, while others show the sweeping progress bar; after 10- 15 seconds, it stops and displays the show title only.

For example, in the Sci-Fi channels, the following shows will not stream, while all of the others will:

The Twilight Zone

Star Trek: The Original Series

Star Trek: Deep Space Nine

Star Trek: Voyager

Fringe

Gene Roddenberry’s Andromeda

Stargate Universe

I uninstalled the Pluto TV app, unplugged the TV for two minutes, and reinstalled the app, to no avail.

It doesn’t matter if I’m logged into Pluto TV or not.

My TV is a C4 with updated software.

Please advise,
