In the past week or so my Windows Media Player has quit playing all web video streams. Things such as CNN Pipeline (even the standalone app which uses Windows Media Player) won't work. I tried using the web player on CNN.com, it also will not find the streams.. If you check the "error details" it says that Windows Media player cannot play any items on the playlist, or it says it cannot play the specified resource type. Also, for a day or so CNN pipeline caused "serious" errors in Windows but I tracked that down to the recent installation of Adobe Photoshop Elements 4.0.
I have tired uninstalling Pipeline and reinstalling it to no avail. I also tried uninstalling and re-installing the K-Lite codec pack to see if it was maybe a codec problem, but that also did not work. I do not have a software firewall, but I am behind a router (tried DMZ Hosting myself and it did not help any) and it has never been an issue before. I also tried upgrading Windows Media Player to version 10.0 to see if maybe some media player files were corrupt. That also did not work and I cannot try a clean install of WIndows Media Player because I can't figure out if there is even a way to uninstall it!
Any help on figuring out why Windows Media Player suddenly decided it didn't want to do streaming video anymore would be very helpful.
