.asx (streaming) file options?

[Fat Tone]

Hi

I'm recording some lectures for students who legitimately cannot attend, and hosting them on a corporate Windows Streaming Media Server.

I'm obviously using a .asx file to point to the mms server, but I'm having difficulty finding out if I can do any more with it. For example, I know you can set starttime and duration parameters as per the example below, and can have multiple entries to create a play list but are there any other options?

<asx version = "3.0">
<title>Time Bounded Clip</title>
<entry> 
<ref href= "mms://streaming1.uni.ac.uk/xx/samples/mediafiles/sample.asf">
<STARTTIME VALUE="00:00:37"/>
<DURATION VALUE="00:00:15"/> 
</ref>
</entry>
</asx>

I'd like to be able to prevent caching. We are controlling access by authentication on the server to ensure those are are supposed to turn up actually do!

Cheers,
