what you posted is good but if they were restored they wouldn't know...lol
I know what stations require a donation number and which don't. Those two stations in question don't require a donation. They are open m3u8. If they don't work, I go download a new m3u and see it the urls have changed.
I guess that's the price to pay for a custom guide. But, I recently removed all the open m3u8 channels. Some Weather, News, Pac 12, Music, Adults etc....
If the channels are dead for awhile that have a donation number in the link, I go and check if they removed it, if not...the donation url's have a tendency to come back, most of the time.
