i've been trying to watch the news videos in CNN and yahoo news and it won't let me. it takes me to media helper, the makes me choose widows media, real player or quick time. when i pick whatever is installed in my computer it says that there is NO MATCHING STREAM.

says this to be exact:

No Matching Stream

The media you are trying to access does not have a stream that matches your default settings. You might try running the Media HelperTM again. Check that you have all required software installed to get the most out of your audio and video experience.

...then it tells me to run media helper again. i can't seem to get it to work. am i using the wrong real player or quicktime? what can i do?
