.ogm difficulties...

[Big D]

I've got a friend who's having some trouble with playing movie filles in .ogm format. Problem is, the front surround speakers are the only ones that actually give out any sound. The others are dead silent the whole time, even though they're fine and work perfectly for anything else. Anybody got any idea what might be wrong, and how to fix it?
Thanks in advance.

By front, do you mean the ones that play standard stereo stuff? If so, then it's probably the OGM only has a stereo and not surround stream audio in it, so it's sending silence to the other speakers - nothing wrong with that It'd be interesting to know which speakers produce sound if you play a normal stereo MP3 in Winamp though, as opposed to testing with DVDs or games that can use 5.1 surround sound.

Apparently the problem was just something to do with the filters that he was using.

What was happening was that the front speakers, but not the rear or centre ones, were producing all the sound. But I believe it's sorted now.
