Macintosh iMovie 5.0.2 Help?

Question

Problem 1:

My friend sent me a clip to be added into a video we were making, however, when I added it onto iMovie (version 5.0.2), the quality was very bad.

Problem 2:

The file was an .wmv file and when playing the clip, in the background there was a "Created with Flip4Mac Trial", which I evidently downloaded for the WMV Player.

I'm kind of a beginner when it comes to Macs, so can anyone help me resolve this issue?

Answer 1

Have you tried the tutorials on http://www.apple.com/support/imovie/

i don't know if it will be much help.
