I ran across this software last week and have been using it since--so far it's ran smoothly with no problems. It's free and it kills pop-up windows. Check it out if you're interested! http://www.vncom.com/e2/default.htm Just a heads up.

And it's easy to use. Apparently, it is also capable of video/audio work, though I have yet to test it out. Here's a link http://www.irfanview.com/
