This is probably a semi-edge case because it involves the Weather Channel, which as far as I am aware is only available via the Frndly docker solution via Custom Channels. So it is not really supported by Channels per-sa, but maybe could be "interesting" for the devs. So I am not making a big deal about it. Other shows recorded from Frndly source channels appear to work fine, so I think this is being caused by the bottom crawl. Anyway, submitted diags after a redetect that failed on a Weather Gone Viral which always seems to have failed detections. Maybe figuring out an issue with an edge case can help improve more mainstream issues.
