see my other post, but your mac is not powerful enough. see the link at http://www.jaman.com/a/download/?osType=mac&videoID=&;theAction=show_download_client&isAddToQueue=0 The h.264 encoding Jaman uses requires a lot of CPU but gets you great quality with a relatively short download time. i.e. the files are 1/4 the size of a DVD with the same quality. If your machine cannot display something like 1FPS of h.264 then you will see no video in the Jaman Player. You could try change mode in the advanced tab in the player from direct3d to safe mode. This has worked for some, but an 800mhz CPU is really just not up to it.
