I had a coupe of concerts in .avi format, and after converting to MPEG-2 DVD format, I noticed Nero Vision Xpress changed the audio from stereo to mono using AC3 Audio mode. I checked if i put any setting wrong, but can't seem to find the Nero MPEG-2 Encoder settings. I tried LPCM and I just geyt noise. Any help will be greatly appeciated. Thanks
