Windows Media is superior in a number of ways:
- better compression algorithm = clearer streaming at just about any bandwidth level
- better market penetration, since it comes bundled with MS OS's
- Real's new marketing concept is basically throw as many ads as possible at users whenever they try to play a freakin video
- Real's support sucks ass (or at least it used to - the adult vid. streaming company I used to work for dumped them last summer, because of poor support and extremely high licensing fees....)
If you are going to do the streaming yourself, I'd go with WM. If you are just looking to add 3rd party streams to your sites, then I'd say give your members a bit of both, because there will always be users who prefer Real over WM (mainly due to an anti-microsoft bias, I think)
Anyway that's my
(well maybe more like 10 cents at the length of this post... sorry, too much coffee this morning)
