5*s from me Rov. Was there a problem with the original audio?...thus the recorded musical overdub? This has happened to me time and time again while trying to record audio of bands playing with a camcorder or webcam microphone. I have some band and personal music footage I'll put up on YTube if you're interested. Also, what's your screen-name on YTube?...need to add you as a friend over there too...I'm "Rousel12" over there also.
Well i use a Canon Xl1 - not the newest model, i know, but sound editing is quite easy.
The screen name is "redmyopia"... i'm not so into youtube, so maybe you try adding me to your friends list :-D Oh, before i forget: very thanks for the comments, man.
And about Bon 'n Brian we 'll gonna talk later :-)
to you too haha. Have you seen the videos I uploaded to my YouTube account? I'll put them here too.
