I'll quickly discuss the debug messages you sent, and will give a few hints.

Konqueror creates a PlayObject for the ressource:

Now it says "Play",

and starts streaming

now some noise from the proxy authentication

OK, Server starts streaming

Konqueror correctly detects the mimetype
> konqueror: got mimetype: video/quicktime

oops. Konqueror tells KIO to close the stream.
> konqueror: streamEnd()

Now, it's quite clear why this happens: Konqueror tries to find an 
Arts-Playobject that can cope with "video/quicktime". However, it also needs 
to find an Object that implements the Arts::StreamPlayObject interface, which 
the xine playobject does not. Currently, there is no playobject that supports 
Quicktime _Streams. Until someone fixes the Xine playobject.

This is the problem, AFAICS. I don't think it's got anything to do with the 
proxy involved.
