I am able to transfer my video from video camera to pc. PC is a HP Windows XP. It has a Pentium 2.8 GHz CPU w/ 1.99GB of RAM.  I am using RESCUE YOUR VIDEOTAPES! Version 4.0  Both during transfer and playback I cannot produce sound.  I do have sound coming out of video camera.  I have tried both RCA and S-Video cables.  Please help!  Thanks in advance
