If you are into video podcasts then I suggest you take a look at what they’re doing with the Miro project.
This is a free, open source video player that aims to make consuming online video a snap. Miro has been around for a while as the Democracy Player so quite a bit of testing has gone into the product already.
If you’re a video podcaster I think its worth a few moments to create yourself an account over there so you can submit your podcast to their built in channel guide. If you’re a fan of online video and want to see who’s there already you can check our their channel guide.
Channels don’t necessarily need to be in the guide to consume them in the player. Like iTunes, you can subscribe to any proper video podcast by adding the RSS feed to the player.
