Oh boy. For starters I would make sure your test machine in it's most default state plays silverlight. You will need a baseline test, a test on a slower network and a test on a faster network. You can throttle the connection to test against this.

I would want to know what browsers your testing in so you can identify potential risks with the different browser frameworks.

I would pair up the requirements with the features of IIS and test against that.

There's soo many unknowns but I think the key thing is that the video can play in it's best available quality, it's minimal available quality and it plays in all compatible browsers. Don't forget to capture the results somehow! When you find out how to do that, let me know haha it sounds interesting.

QA is about concrete formalism.
===========
test smooth streaming in detail.
==============
is not detailed, and very vague from a formal QA standpoint.
We need to formalize the statement.

Formally, a smooth curve is known by [http://en.wikipedia.org/wiki/Lipschitz_continuity]

That means, in essence, a small change in input would end up having a small change in output, and the system is called smooth.

That means, there would be a cutoff between No_Of_Frames/per_sec intended to display vs No_Of_Frames/per_sec displayed.

That is the guy /or the automated process who asks the streaming server to give data at a particular bitrate, should stick to that, and server must stick to this definitive bit rate.
Any disparity fails the test case.

You probably need to write your custom media stream consumer, but that is easy -- as VLC is open sourced.

Please feel free to add to this.

Actually from control system standpoint, it is called BIBO stability, Bounded Input / Bounded Output stability.
