The codecs aren't dependent on bit that applies to the additional software klite installs in addition to the actual codecs.
That's part of the reason I quit using klite sometime ago and started using the cccp pack instead.
I doubt it's a codec problem though as they wouldn't work in media player either if that was the case.
Do you get sound using this program. VideoLAN - Official page for VLC media player, the Open Source video framework!
sorry to ask you to install yet another player, but it's the only one I know of that works independently of the system codecs.
