Downmix 5.1 to stereo or use direct stereo? 2005-04-13 03:11:01 Hi. I have this DVD which has audio in both 5.1 ch and "Stereo Surrond". I am going to rip this to XviD in order to watch it on my PC with stereo headphones. Which sound format will be better? I guess using the stereo directly is much better compared to downmixing 5.1 channel audio to LAME--aps stereo. What do you think?Also, in case of stereo, shall I include the ac3 stream itself or convert to mp3? Will a movie with ac3 sound play on any media player (for example, Windows Media Player) without any additional software? Thanks.
