Maybe I'll turn Thursday's into 'release days' and round up all the great podware that's been released in the last week.
I've played with Podcast Generator before, but haven't stuck with it. Not because there's anything wrong with it, but because I was with a host that took care of my feed generation and all.
Podcast Generator is a free PHP script released under GPL which allows to upload media files via a web form and automatically create podcast rss 2.0 w3c-compliant feeds. It also features a web administration and a dynamic web page displaying new podcasts.
If you're in the business of hosting your podcasts, this baby might take the pain out of hand-rolling your own XML files for your feed.
