It's mms and wmv so you might still have trouble on your Mac depending on what kind you've got, but at least it's a start.

You are a brilliant man. A pure genius.

No worries there...I got plugins to my quicktime pro up the wazzu. As well as WMV player itself and a billion other things. One of macs good points is all the freeware. :mrgreen:

I don't suppose you'd care to elaborate on that a bit more? On my Macbook Pro none of the above listed streams will play using either Quicktime (with Flip4Mac installed), VLC, or MPlayer. Of course I can always boot to windows where they all work fine, however I'd rather not have to do that. Do you know of some other good streaming media player for OSX? (I'm not really satisfied with any of the ones I listed above).

Sorry Imron, I spoke out of term. I said that with assumption as they were wmv format as I was running out the door to go to class without trying. 出丑了. Sorry, I will try other things because unfortunately for me...I partitioned my harddrive for video capturing before I knew that you had to do boot camp and haven't had to time to reback-up everything bootcamp and then install windows, so I'm stuck for now.

Going to try out that perian now. Will let you know. But if you find it let me know.

Here's a link to the same interview that will work on Macs (works for me with both Quicktime+Flip4Mac or VLC). It seems existing streaming software on the Mac doesn't take into account redirect messages in the MMS protocol, hence it was failing to open the above listed files which were getting redirected.

How did you find this imron? Is there some way we can use this on other mms wmv streams?

My background is in computer programming, and being fed up with what's currently available with mms streaming programs for the Mac, I decided to have a look at the mms protocol specification myself, write a small test app, and see what was causing the error. It turned out that everytime a connection was made to the original files, the mms server was sending a redirect message to a different location. So I checked with that new location, which redirected me again somewhere else. Finally that 3rd new location worked and so I posted it here for those interested. Anyway the test app is *very* basic and hacked up and not really suitable for release. Also, it only deals with the handshaking/connecting part of the protocol, not the actual downloading of streams, so it's probably not really going to be of any use to anyone.

If I find the time I might consider writing a proper stream downloader for the Mac, as I've been meaning to find an interesting project to have a play with programming under OSX, and from my experience so far, OSX sure could use it.

Yeah probably, but the two open source projects I know of with streaming (VLC and MPlayer) are far more than just a simple stream downloader, and also they are ports of applications from other operating systems with most of the work already done (plus from an aesthetic point of view, they don't really behave and feel like a native Mac application). Part of the purpose in me writing such a program would be to get familiar with programming under OSX and from that point of view writing something from scratch would be far more useful than just fixing up a small part of an existing application.
