sound from video very distorted after transfer to DVD

I transfered a video of my band to DVD with the software that comes with the Vaio, click to DVD. the sound was a little poor to begin with, but after transfer to the disc it came out even worse than the video. my theory is that it was recorded mono and I don't know which side the sound is coming from left or right so I have both plugged into the capture card and there's some kind of weird bleed distortion coming from the side with no sound, but I don't know for sure. help please.

 

I can not tell you why you are Haveing Audio distortion problems but I can tell you that there are ways of Cleaning up the Audio so it sounds Better....

After Captureing you can demux the captured file into a seperate audio and Video file and then Load the Audio file into a good Audio editor like "Sony Sound Forge" or "Goldwave" and use there Audio filters to Filter out the Distortion and to adjust the Equalization ect untill the audio sounds more the way you want it to and then render the audio as a WAV file or a Dolby Digital AC3 file (If useing Sound Forge with the AC3 Plugin) and then use the New Audio file and the Video file to author to DVD with your DVD Authoring Program....
