Does anyone have suggestions on places to get music, audio and video that can be added to videos I'm creating. I'm capturing and editing home movies from my camcorder and would like to add background music and other things to the content. I'm also getting my son involved with creating DVDs, to let him expirement with different things.

I bought Video Explosion Deluxe (SF Vegas Video OEM), which came with some 30 to 90 second music clips, along with some video clips. I have also found some content at http://www.screenblast.com . I am looking for any other suggestions on places to get music and video contect. Free is always better, but would pay for it if it is worth while.

Is something like SF Acid worth getting to create loops. It could get rather costly if after buying a few loop content disks. I also don't really want to spend a lot of time creating backgroud music. It seems like I don't have much extra time anymore.

Any help would be appreciated.
