|I've now found this in your other post (double posts are a nuisance):|
"IE monopolized my videos downloads to the point no video player can execute them. Videos that are downloaded are stamped with IE logos. Thus these video refuse to function in playback with multiple videos player which used to play them nicely"
That is not an IE issue. You need to give an example of the file type of these downloaded videos (such as .wmv .mpg .mp4 etc). The files need to be associated with the video player of your choice. You right click any video of each type then select "Open with".
I will mark your other post for removal.
Always pop back and let us know the outcome - thanks
