I'm learning Adobe Premier Element 4 to edit DV (Home video and seminars) tapes but two issues bother me recently.

1) Where can I get (or free download) background music clips ? I'm using personal music CD collection to add tracks but the selection is limited. I need some short and right to the video mood music clips.

2) In seminars shooting, I had two video cameras shooting from different angles. During the post poduction, I have difficulty to syn the speakers' lips if I link two video clips together. For example, I take the camera 1's video clips of whole seminar hall wide shoot and add the speaker's close up clips from camera 2, I have problem to have the second video clip lip syn to first video's audio track. Do I need other advance video editing software to get it done ?

Many thanks.
