Adobe Media Player prerelease 2 is available on Adobe Labs. It is improved from a user perspective. Also, there's an easy way to start your own iTunes or AMP channel with custom branding using a Blip.TV account. Bob Donlon walked through this the other night at the SF Cutters meeting and it's quite easy. When you log in to a Blip.TV account, click on distribution in the blue panel at the left to create various RSS feeds.
