I was browsing to a website today that actually required I have Real Player installed. Real Player? I definitely would not put that annoying Spyware/resource hog on my PC. Then I remembered I installed a version of QuickTime Lite to view sites that required that, so I figured there would be a cool alternate version of Real Player out there. Sure enough! Real Alternative is a great way to bypass installing the whole Real Player pig. Also, when installing it you can choose to just install what you need.
All I needed was the plug in for Firefox and that is all I installed! Now I can view the website which requires Real Player.
