degradation in video quality

[movie maker newby]

Why is that when I copy a clip from the collection to the storyboard that the
quality in the storyboard is markedly degraded? How can can I prevent this?

But it does effect it. A movie screen shot captured using Windows Media
Encoder is virtually perfect at full screen before it's edited in Windows
Movie Maker. Once edited, it's illegible.

Doing all that still results in degraded movie files. The WMM movie is much
worse quality than the original file recorded by WME.

I don't know enough to choose the settings. Is there a CP I could
download/import?

I'm getting the profile thing to work but the quality of the output movie is
still not quite as good as the input and the size of the output is a lot
larger. What can the settings be that would make the output the same quality
and size as the input? Note that I'm using SlideShow-1024x768WMV9.prx as I
downloaded it.
