SEIU and UK union use videos

I just got a link to [Driving Up Standards | http://drivingupstandards.org/index.asp?Type=NONE&SEC={03E45FBF-FBCE-469A-9C90-DF36A091B713}], a "[Service Employees International Union] and the [Transport and General Workers Union] ... new transatlantic partnership to hold UK-based bus companies accountable to employees and consumers in both countries..." project. I was immediately impressed by their use of [worker video clips | http://drivingupstandards.org/index.asp?Type=B_BASIC&SEC={E9CB7F18-6065-4E54-8212-DAF75BB65B04}&DE={0988CDF2-2E42-4179-B34C-A54B5182D80D}], the only problem is that they are using Real Player. Which in my limited knoweledge of video is not open source and is particularly difficult to distribute further than the website. (I just started to try and do something with [video | http://markdilleywashereat.castpost.com/31014.html]) Any folks out there that know more about video for the web, compression, format, etc? I think it is a great idea for communication! (p.s. Steve, how do I make this show up on the front page?)
