I just upgraded my DVD author 3 to the latest version and I ran into a problem. When I go to output my video to DVD, I get an error message that says "Invalid sample format error 0x80048002", Also, audio is not present during editing. However, the file plays fine in all other media players. I used Gspot to check the properties and the file is a Divx vid with mp3 audio, codec 0x0055. The strange part is that the free version of TMPGenc 2.52 recognizes AND plays the audio. I have AC3 codecs installed as has been recommended here before but I need help in figuring out what that error code means. Any help is greatly appreciated. Thanks P.S. I also added video clips which I previously edited in DVD author 3 and they worked fine, i.e. audio during editing, etc. So I am sure that upgrading to the latest version did not cause my issue. I must also add that the 2 vids in question came from the same source file. Other files I added to the project play audio fine during editing.
