Sorry, yes, Adobe Reader is the name for the 'normal' Windows reader.
As you don't seem interested in the DRM issues, this is probably on the wrong forum (Digital Editions)
If you want people to read files that require (free) Adobe Reader, I guess they will just have to install it.
It would be handy if there was some way of making readers that don't support the video put out a message telling them to install the full reader, though.
Maybe there is (equivalent to alt text for images in html) ~ I'm afraid I'm not up on pdf details.
