If your trying to play a file and it tells you to d/l something from the internet, just delete the file and search for something else. You shouldn't have to d/l anything in order to play a file, and definately don't d/l activeX files unless it's from a trusted site and your know why your d/ling it.

For videos, stick to avi's and mpg's. Stay away from wmv's, mov's, and asf files. See What you should know about WMA & WMV Files
