Cross-platform media player Boxee has added support for full length videos from ABC.com to it's Mac client. Boxee's Ubuntu and Windows software can't handle ABC video yet, but support is on its way.

Today's update is significant, because up until now ABC's web video player has been something of a walled garden. While CBS, Fox, and NBC have been making their videos available for distribution on Hulu, Fancast, AOL TV, MSN TV and a variety of other outlets, if you want to watch full length episodes of ABC shows you're pretty much stuck with the ABC web site.

ZeeVee's ZViewer does offer a full screen interface for perusing ABC videos, but video playback is rather clunky since you have to click a button on the screen to resume playback after each commercial. Boxee lets users navigate through the whole video with a remote control. No mouse required.
