After switching from Philo to Sling Blue, was disappointed with the lack of TVE apps. Philo has about 25 TVE apps that import into Channels, but Sling Blue only has, A&E, Nat Geo and Fox News. Plus 80 FAST channels.
After following the post by tmm1 "Experimental: Stream Links from the Guide via Custom Channels". I found a work around to the lack of TVE apps for Sling. It only gives me a program guide and does not import the Sling channel into ChannelsDVR. The Channels program guide is far superior to Sling's program guide. It's not a replacement for the lack of TVE apps for Sling, but it allows me to see what's on and when. I than go to the Sling UI and watch or record using the Sling app.
