Please use this thread to discuss experiences and channel availability for YouTube TV.
Current Status: Moderate support for TVE, including many major channels.
Note that if you have 2FA enabled on your Google account, you will not be able to use it with Channels DVR. You can create a secondary family account login and use that instead: https://support.google.com/youtubetv/answer/7251139?hl=en
If you have Channels DVR running on the NVidia SHIELD, then YouTube TV login is not supported.
For best results, before adding your YouTube TV account to Channels DVR, first visit https://nbc.com/live and login there to authorize TVE access.
