Hi, this is my first time to use TMPGEnc. I converted a 60 minutes music vedio from regular avi (1 hour = 12GM) to VCD. The vedio is good. However the audio is very bad. I can hear the songs with shrill and sharp noise. However before the conversion, when I play the audio in "Audio effect", the sound is good. Should I use LAME or any codec in "enviornment setting"? Should I check "reduce noise"? Please help. Thanks.
