While playing the asx file the player stops on the first ENTRY and waits for
buffer to fill even when the broadcasting PP (with wrappers) is active and
the standalone stream (mms://server/broadcastPP) works just fine. Why is that?
(when i set the param "ShowWhileBuffering" value to "false", the player
plays the second ENTRY, but that's not the case)

ASX file:
<ASX VERSION = "3.0" >
    <PARAM NAME = "encoding" value="UTF-8" />
    <ENTRY CLIENTSKIP = "no">
        <REF HREF = "http://server/loading_please_wait.wmv" />
        <PARAM NAME = "ShowWhileBuffering" VALUE = "true" />
    </ENTRY>
    <ENTRY CLIENTSKIP = "no">
            <PARAM NAME = "Prebuffer" VALUE = "true" />
            <REF HREF = "mms://server/broadcastPP" />
    </ENTRY>
</ASX>

Publishing Point:
- type: broadcast
- source: http://encoder:port (works!)
- wrappers:
<?wsx version="1.0"?>
<smil>
    <media src="C:\start.jpg" dur="3s"/>
<media src="%requestedURL%" />
<media src="C:\end.jpg" dur="1s""/>
</smil>

Your server side playlist mandates 3 seconds of the start.jpg file
before it even begins to play the video. Is that what you meant ?

How are you determing the (player?) buffer is being filled, and what
are the buffering settings in WMP Tools -> Options -> Performance ?

Yes. Everytime a user connects to the live stream I want him to see a
picture or a short movie (a kind of front page). The 3 sec time isn't
nessesary, I can also insert there a 3sec wmv movie or something. Nothing
changes in the problem case.

It plays the first ENTRY (http://server/loading_please_wait.wmv) (progress
bar goes to the end) and stops showing the last frame of the movie (I guess
it waits for the second ENTRY data - live stream with wrappers). I tried
setting the buffer in WMP to either 1sec, 8sec, default, it doesn't help.

Some more info: In wrapper playlist file, when I remove the first "media"
element (first add - start.jpg/wmv) it works just as i want it to work - the
loading_please_wait.wmv hangs when the Encoder isn't sending data and as soon
as it starts the playing resumes (but without the necessary first add - the
front page).

Cheers.

One more thing: the stream mms://server/broadcastPP looks fine (start + live
+ end).
