Hello I'm trying to burn a DVD froma divx file i downloaded and I am forced to ncode it using low bitrates because the pcm wav file i'm creating is incredibly huge. Is there any way i can use a format other that pcm (i.e. dts, dolby digital, etc.) that would take up less space? I also noticed that when i play back one of my new dvd's on my settop I can barely hear the vocal and the music, background noice is very loud. Is it possible that the divx file was originally encoded in a multichannel format? if so, how do i keep this when burning my dvd?
