Forgot to mention, Android Podcast Addict is a great podcast app, and for windows is Groover Pro.

Both supports opml file that saves your subscriptions to the cloud. So you can sync on your devices.

Podcast addict supports youtube links also, both support video podcasts.

And why not use Itunes? Itunes likes to download all your podcast feeds, and can eat lots of disk space if you have many subscriptions, use a dedicated podcast app/program.
