Then manually add that to any podcasting app. PodcastGuru is great at video so thats what I recommend.
I also added it to podcastindex.org so it "might" show up in the podcast apps search under HODL but this is new ground were breaking here so your milage will vary.

Here it is with all my other podcasts in PodcastGuru.

TLDR manually add the RSS Feed to PodcastGuru like we did in 2007. Also works the same for any castr.me Rss Feed.
