No center channel sound when playing movies in MCE
A strange problem cropped up for me in MCE (I am running XP MCE 2005 RU2) a while ago that didn't occur when I first set up my HTPC in Dec 2006. When I play a DVD, either directly from a DVD or one that is ripped to my hard drive, I don't get the centre channel audio which contains dialogue. I am using the default media player - I did temporarily switch to TheaterTek (I bought a license for this a while back) but I switched away from it as my remote didn't seem to work properly with TT.
I do get background sounds but that is all. This does NOT happen when I play movies using a third party software DVD player.
I have DD5.1 set up correctly and TV properly plays in 5.1 (I have an HD tuner card in my PC) and I can play back recorded TV with DD 5.1. All other content plays back properly as do Divx/Xvid movies that aren't DD 5.1.
Anyone have any ideas why this might be? Could it be a codec problem (I believe I am using the Nvidia codecs that come with TheaterTek)? How about a language setting problem - I have tried playing around with the language settings without luck.
