Source link needs to start with "http://"

Our system, that had been running for years, broke after a recent DivX Web Player update.

Turns out the source link now needs to start with "http://".
Let me demonstrate...

This used to work, but not anymore:
param name='src' value='streamer?file=video.divx'

Now it needs to be this:
param name='src' value='http://localhost/streamer?file=video.divx'

So i guess the player no longer supports relative URLs?
Why ??!! Please tell me the reasoning behind this ... it used to work just fine...

And one more thing: I think the link also needs to end in ".avi" or ".divx".
Can anyone confirm this?

Oh and another thing: the code generator on your website doesn't give a warning when the source link doesn't start with "http://"...
I really think it should!
And even the webmaster SDK handbook doesn't mention this!
