I've been trying to play ANY video from the following website:
http://www.telecinco.es/ (Spanish) and I get this error every time. Here's a
direct link to a stream to see this error:
mms://media.telecinco.es/telecinco/ot_ba/051127risto.wmv.

This works perfectly fine on my XP box with the same network settings, so
I'm guessing I'm missing WMP9 codecs as it states on their website to
download. I cannot find any WMP9 Vista compatible codecs, however.

Also, I played around with my firewall settings in Vista and router and
nothing has helped. Additionally, mms audio streams from other sources seem
to work just find, so I don't think it's the protocol.

Please help!
