I'm having some trouble with the RSS feed for my podcasts.
Seems that once something is posted, the feed is not refreshed. So if you make a mistake, then you're kinda over a barrel.
I have two different programs coming from the same blog, first one works fine, but the second one broke at program 13. The RSS Feed never recovered, despite my going into the post and correcting the enclosure, and double (tripple) checking everything.
The aggregators, and feed crawlers all report an error. So programs 14, and 15 have not been picked up because of the break at program 13.
I wish there were some other way of editing the feeds apart from entering your info, and crossing your fingers.
