A crossover is something that filters out and redirects frequencies of a certain range. If a very low frequency signal is sent to your speakers, the crossover should redirect it to the subwoofer. If a higher-frequency signal is sent to the sub, then it should be redirected to the satellites. Get it?
Music plays in stereo and doesn't have a separate subwoofer channel. Games can play in surround, but I don't think they have a separate LFE (low frequecy effects) channel, so your crossover network would have to take care of that. The reason why you can hear the sub in DVDs is because I'm pretty sure that they DO have a separate LFE channel that is sent to the subwoofer. This means that the crossover wouldn't have to do much for DVDs.
Like I said, if your soundcard goes to a receiver or amp and then to the speakers, try adjusting the settings on the receiver/amp to find a crossover setting. The receiver itself can then redirect the signals.
