I don't own a mac (yes, i know, this IS Mac Help but I'm hoping someone can help me anyways) and when I watch DVDs my sound is sketchy, not at all regular DVD sound quality. I have fairly good speakers, but the problem is still there. I have balanced the volume control with the speakers. Could it be my sound card? I'm not sure what it is, but my DVD rom is a CDRW/DVD drive 32x10x40. Please, suggestions?
