Some web sites use encryption when streaming video or audio. Replay Media Catcher cannot download these encrypted streams. However, the vast majority of streaming media is not encrypted. Sometimes it just takes a slight tweak to allow Replay Media Catcher to pick up an HTTP content type that it may not know about.
In Replay Media Catcher's Properties, click on Protocols. Here you can add additional content types. Or simply drop us a line and we will test the site for you and provide you with the proper settings to make it work if possible.
