Well that is quite the video player setup!.... but it may not be as clear cut as it first seems. Did you click on all the buttons to see what happens?
There are really only two choices that match what you are attempting to do..
Windows Media and Flash Media achives...
want users to select a player e.g[flash, windows media player etc]..to play a video....I am creating a video gallery so when you click on a player it shows on the page then u can now select the video you want to watch.
The other selections are for Live Streaming video... and I assume the reason for all those choices is NOT to give the viewer a bunch of good choices for viewing the Live Stream, but rather to try find one type of file that will work on their machine.... so if this doesn't work..try this one or that one.
That is certainly one way to try cover all bases.
Anyway, it certainly is possible to provide multiple video file types. But again I warn you that it can be confusing for the viewer and implementation will greatly multiply your development time. I really wonder why you would want to provide 3 file types when 1 would do? Do you have the video editing software to provide multiple file types?
Speaking of file types, Windows Media (wmv) really only play in Windows machine (just a small portion of all video devices)... not Mac or iProducts... Flash plays in nearly all Windows and Macs .... coving a much larger segment of audiance, but not iProducts.
So you really need to add a third type targeting mobile iProducts if enhancing viewer experience is your goal.... using a QuickTime mp4 or m4v....
or just use 1 single mp4 file and a good video player, (like JWPlayer or Flow player... as used on the link you sent) and cover all bases with just one video file.
Here is an example of a video file using JWPlayer which plays on PCs, Macs, and iProducts:
Anyway, best of luck!
