I have wmv files on my webserver that will open an Internet Explorer window and play the video on my XP laptop, which is what I want to happen on all computers. I have tried to play the videos on other computers and Windows Media Player opens, rather than an Internet Explorer window. When Windows Media Palyer opens I get an error message. On XP machines, it says that it encountered an error when connecting to the server and that the security information from the erver could not be validated. On Windows 7 PCs it says that there is a codec error. Both XP PCs and Windows 7 PCs will play the video after clicking "Close' on the error message and then clicking Play. The website that contains the videos is a secure site. I have noticed that IE 9 and IE 10 will ask whether I want to Save or Open the file. I do not want anyone to be able to save the file, so if it will automatically play in an IE window, like on my laptop, then they cannot save the video files.
Any help is greatly appreciated.
