I'm trying to play videos from a site, its a MP4 and when I click on it loads but then I get an a message of "Cannot play video, Sorry, this video cannot be played." The video also gives me the option to play it as a WMV, when I download the WMV version it wont play. All it does is play the audio, the actual video won't play. Am I doing something wrong or do I need to download an app, if so what app? I'm using the default browser on the Hero. Thanks!
