I read on the Dvbviewer forum that it won't show every codec installed on your system, only codecs it can utilize. I know the Cyberlink codecs work because I use them, have you downloaded a trial copy of PowerDVD? I think they are now up to version 9. Just install the program and the codecs, video and audio should show up in Dvbviewer, they are all you really need to get started and it won't cost you anything.
