CW Seed is a 24-hour tv channel that broadcasts lots of shows for free on their website: https://www.cwseed.com/watch-live/
It could be a good addition to the existing free channels list, which is a bit news-heavy at the moment. CW Seed airs pretty much just tv shows produced by CW during the past decade or so.
This was already posted about recently, a search will help you locate the thread. Since this is not a linear live channel that Channels can get guide data for, it’s unlikely it will ever be officially added. However, I think you could add it as an m3u source, which is discussed in that other thread.
