Multi-screen player?

There are several players for Android that support multi-screen/multi-view using the ChannelsDVR, M3U feature. Right now I use CosmiDVR. My question is, are there any for Apple TV? Thanks in Advance.

Here's a few topics (I don't use any of them)

I went with iProTV and QuadStream. Both are working well. I just need a Siri remote to get to the Multiview mode by swiping up, which I can't do. Settling for PIP and time-shift for now which is great, because it will do two channels simultaneously!
