Ok, I ran the file through gspot to see exactly what codecs were used in the movie. Here is the screenshot of the result-- http://www.escic.com/cr95gst/gspotresult.jpg As you can see, the video codec is Divx3 and the audio is MPEG1-Layer3. When I converted the AVI file to MPEG2 using TMPGENC everything goes smoothly but there is no sound whether I play it in the DVD player or on the PC. As far as I can tell, I looked through all the options on NERO 6 and TMPGENC and didn't see anything to resolve the issue. I also did a search on here using the phrase "no sound" and all I saw were threads in relation to AV3 encoding. Any ideas or suggestions? BTW, this is my first post here... Great Forum and Resources here!
