New cord cutter trying to use locast for local channels plus sling TV (despite limited TVE support). I'm only on a 3 day trial of sling now but I was able to, for example, use my credentials from sling to watch ESPN (via https://www.espn.com/watch) on the same laptop I use to manage channels.
Of note, the actual channels server and DVR are both being run from an nvidia shield pro. However, when I try to add sling TV as a TVE provider for channels, ALL I get is a single message at the top "no login form found".
I then tried YTTV (before realizing it was not compatible with the shield)...interestingly I get the exact same message.
Edit: I should mention that locast is working perfectly! Finally, sorry if naive but when I go to add source, it does say TVE is beta - I don't know if this is always the case or if I have a beta version...
