>Whenever I've played videos with Media Player, they always seem to buffer for some time before playing starts. Even on broadband this can take a while. I'd say 15+ seconds is normal, 60 seconds is rather long.

Yes, this is rather long. I even asked myself the question of knowing if it was downloading everything before starting to play it. We have configured everything on the server to stream. But, I'm not sure if it is streaming or not. I guess the best way is to have a very big video, such as 50 meg, and see if within 60 seconds, it will play. Within the same timeframe, it will stream as the download would take longer.
