Thanks Will and Weasel!
My biggest problem is cnn.com. The Adguard rule posted by avatar-arg will remove the video window, however cnn.com seems to force the video to load and run before the Adguard scripts run.
The page loads. The video loads and begins playing. Then Adguard's rules run and kill the video window, but the audio can still be heard.
I'll see if I can figure out how to modify the script, but I will admit that I'm a novice at it, so I don't know how successful I will be.
If I'm successful, I'll let you know.
