Jong, it is impossible not to have a video decoder (like LAV Video) in the filter list.... you can not connect a splitter to a renderer. To see what is happening either post a screen shot (like I did) or else on the playing now window do a "right click --> direct show filters --> copy graph info to clipboard" then post the results here such as:
