Is there a DVD you can download that actually works?My computer came with PowerDVD,but there was no audio,although I followed all the instructions.So I downloadedthe newest version,and not only was there no audio,there was no video.I tried WinDVD and Zoom Player,and it just said"no media loaded'.I`m pretty new at computers,so maybe I`m doing something wrong,I don`t know,but any helpwould be appreciated.
