My recommendations, don't use WMPlayer. You leave out a lot of potential viewers (MAC and FF do not come with WMP pluggin). After all, it's not which player you put on the Web page that determines if the viewer can see/hear your content, rather it's if the viewers browser has the correct pluggin to play the media. Flash is by far the most cross browser friendly. Google for Flash audio or video players. Lots of freebees out there, including ones with playlists
If your read my other post, you know that your posts will be up for "Peer review".
First off, the first paragraph of your post is off focus and not factual.
Has this seemed impractical because video loads too slow, takes to much web space or just seems to hard to understand.
Dowload speed continues to increase and many hosts will provide unlimited Web site space as well as unlimited bandwidth, making hosting videos on web sites very common and inexpensive.
In your second paragraph you mention
very difficult for the average individual to add video files to their websites
This is a Web Developers Forum. Viewers are here because they are NOT average individuals.
Windows Player simplified this process but still had limitations. It played a few formats, but not the streaming .swf (Flash) files
Windows Media Player is no more easy or difficult to place on a Web page than any other media player. And Flash .swf files are not "streamed". The .swf file is the player, not the video file, which may or may not be "streamed". Almost always video files are progressively downloaded and not streamed.
Best wishes all,
