I am running DVDfab Platinum 126.96.36.199. I have been using this for several months. When I view "previews" using the software, there has never been sound associated with the preview. I finally read the tutorial, and I believe I have an issue as I should have sound (I believe). Wnen I go into common settings, general, preview: I only have two check boxes under playback: "show preview window automatically", and "play selected source automatically". In reviewing the help docs, I believe I should have additional selections for "decoder" (internal and direct show) and "direct show filter" (video decoder and audio decoder selections). I have neither of these, only the two playback items. What do I have to do to get the audio working? I also did not register on-line so I cannot upgrade my license to a 5.x copy as I cannot remember what I did. I do have all my 4.x info for registration however... So, how do I get 4.1 working with sound on preview. Thanks!
