[QUOTE="CyberSimian, post: 1170774, member: 141969"] I also encountered this when watching DVDs, and also when watching a very small number of TV programmes. It is the problem explained by mm -- the DVD or TV programme has a five-channel soundtrack, but I was watching with two-channel stereo and I had not enabled "mix down" in the LAV settings. I enabled mix down using the default settings (0.71, 0.71, 0.0), but I found that that was still not enough, so I increased the central bias and reduced the "surround" level (0.80, 0.60, 0.0). Although DVB-T2 has the capability to carry multi-channel sound, I think that at present very few programmes are transmitted this way. The only two that I have noticed are "Remember Me" (a 3-part contemporary ghost story starring Michael Palin), and "Wizards and Aliens" (a SF serial for juveniles, but enjoyed by older juveniles too ;) ). I suspect that the BBC use a multi-channel soundtrack only for "prestige" productions, where significant foreign sales are anticipated. However, big-name films may be broadcast with multi-channel soundtracks (but now that I have enabled mix-down, I am less likely to notice this :D ). -- from CyberSimian in the UK [/QUOTE]
