One of the videos had the original audio from the camera, so the audio is the default setting of NTSC DV. And for other editon I take a MP3 file to make a “kolash” with the original source videos. I use the default transcode settings of Ecore, so the audio is dolby digital… OK another question, the recompression issue that you say, is on Premiere or in Encore, because the .AVI files sound fine. another abservation… the sound problem is only when I play the DVD in my DVD player (APEX AD-1225, very cheap thing), but when play the same disc on my PC the audio are fine… It posible that the DVD player are damage or something, because before I made exactly the same proccess of editng and DVD authoring and this DVD player work great.
