All of my Discovery channels no longer work on my setup with YTTV. Even checked the experimental rewriter and it's a no go
For me Discovery only allowed a few logins within a time period and I had to repeat the process on the channels that didn't get logged in over the course of a few days.
Yeah still not working for me
Have you tried doing the Update Password trick and then rescanning those channels individually?
Steps 9 & 10 here TVE Troubleshooting tips
Just tried that and still not working
Are you running the latest pre-release DVR Pre-Release Notes - Beta Community / DVR Beta - Channels Community
All I can offer is what I've written up in those TVE Troubleshooting Tips, which is a compilation of the most likely fixes, ending with submitting diagnostics when you've exhausted everything else. I've ended up there a few times myself using Xfinity (which is usually pretty good with TVE).
Deleted YTTV and added it back in and now it works. Don't know how much it will last though
Discovery channels require reauth every 7-8 days for me w/Xfinity. Pretty sure it's the same for all providers.
