Regularly, any video I'd try to watch opens just fine, but on a password protected site, when I click on a link to a video (.wmv) the file won't open, no matter what video app I try. I assume this is because the video is password protected, but the app doesn't know to ask me for a password? I'm not entirely sure. I'm using a motorola xoom and the dolphin browser. I've tried MoboPlayer, MX Video Player, and RockPlayer. Any suggestions?
