Per the current spec:

If the file.wmv is present, the first of the following plugins to be 
supported:

 1. clsid:6BF52A52-394A-11D3-B153-00C04F79FAA6
 2. clsid:22D6F312-B0F6-11D0-94AB-0080C74C7E95
 3. clsid:9BE31822-FDAD-461B-AD51-BE1D1C159921
 4. The plugin that supports whatever the MIME type of the file.wmv is, if 
    it had a type and it wasn't "application/octet-stream".
 5. The plugin for "video/x-ms-wmv".
 6. no plugin.

If the file.wmv is absent, the first of the following plugins to be 
supported:

 1. clsid:6BF52A52-394A-11D3-B153-00C04F79FAA6
 2. clsid:22D6F312-B0F6-11D0-94AB-0080C74C7E95
 3. clsid:9BE31822-FDAD-461B-AD51-BE1D1C159921
 4. no plugin.

The only difference between the two files is the data="" attribute on the 
<object>s with classid="", but per spec, if there is a classid="" 
attribute, the data="" attribute doesn't matter.
