kak2a2,
Roxio Creator 2010 Pro is indeed a
heavy application, making it slow to install and utilize. I advise you to uninstall Roxio, and then download and install
ImgBurn. Most people here in SF highly recommend that app because it's lightweight and fast.
Media Player Classic with K-Lite is a great combination, but you can try out
VLC media player or
Shark007's Free Codec solutions. Most people use and recommend those as well.
