I want to use online animation to demo software. I have experimented with Adobe Flash Player (x-shockwave-flash ?), captured screen animation using both CamStudio and Snagit, and converted the resulting *.avi files to MacroMedia *.swf files (using the free CamStudio avi to swf converter), which I then upload to my server and link to an ASP.NET webpage.

See: http://www.pliatech.com/flashtest.aspx

The problem is that there are alot of extra frame-like lines that appear. Nice online video demos don't have these lines.

What am I doing wrong? How can I get rid of these annoying lines?
