As much as I do appreciate it, for news specifically for this feature to be of interest, I've got to have the ability to choose between whatever local and other national, international news channels are available on the service. (i.e. not just Fox News, MSNBC, CNN and BBC.) But yeah, this sure is better than no multiview at all.
I'm still using IPTVX via Channels DVR for the most part, I've dialed it in with the favorite channels I enjoy choosing from most (across the board with antenna content, streaming and ADBtuner channels) and it allows for the most flexibility. Of all the choices providing on-the-fly multiviewing, it works the best for me. I just wish the overall UI of the app was more polished, specifically with regards to multiview, and that we could save and re-arrange the grid content in a more elegant and intuitive way.
