Video Podcast Episode
When considering a podcast with video (video-cast) its worth considering playback using hosted video like Vimeo and YouTube - especially if the site is published to the EverWeb server. Video files take up a lot of storage room.
The downside to this is that it is not possible for visitors to download a zipped file of the video to view at their leisure.
Of the two, Vimeo is much preferable - especially for professionals who need to ensure the visitor gets to choose the quality of the video.
