This program allows to subscribe to YouTube video feeds as podcasts from iTunes, PSP, and other podcast software, to watch them later or offline.
Program uses Java Web Start technology. You can read about it at http://www.java.com/en/download/faq/java_webstart.xml . Program requires all permisions to your computer, because it runs local podcast server and creates outgoing connections to YouTube.
Server must be running all the time when you doing updates (or all the time when podcast application is running, if updates are automatic)
Check that podcast URL is accessible. Just copy/paste URL into web browser. In Firefox you should see correctly formatted web page with pocast items, in other browsers you just may see a lot of text. If there is error that host is not accessible, probably application found incorrect host for your computer. Change it manually to correct host name or to IP address.
