If you get a chance, would you check that this recipe is working in 0.7.20? Check the built-in, not the one posted here, and check it inside Calibre, not your test environment. I was seeing some odd behavior. There should be more than 3 feeds, and the name of the epub should have "Issue" inside square brackets, as in "[October 2010 Issue]" and not just "[October 2010]".
