Why can't I keep my songs on my ipod and still sync a movie?

Question

I am new at this.. I bought a movie and want to sync it to my iPhone/iPod but a message tells me I will lose my music when I sync the movie.  Why can't I have the music and movie?  Why does one replace the other? I appreciate the help you can give me.  Thanks!

Answer 1

Thank You.  I will work with the information you gave me and see if I can
learn what is going on.

Subject:        Why Can't I Put My Clips on Certain
Video and Audio Tracks?
Any kind of source video can go on any video track in a sequence.
Therefore, it's the audio that is causing the problem.
Your source clips can have three potential audio channel assignments
(actually, there are more, but they are just combinations of these three).
A source clip can have mono audio, stereo audio, or 5.1 audio.
Correspondingly, there are specific types of audio tracks that must be in
a sequence in order for source clips with specific source channels to be
edited into them. If you drag a clip to a sequence, and there is not an
audio track that matches the source channels of the source clip, a new
track will be created that matches, e.g. a stereo track for a stereo
source clip. However, if you try to insert or overlay a source clip into a
sequence that doesn't have a matching track, the audio will be ignored.
In the sequence, you can tell what sort of audio track you're working with
if you look for the little speaker icon that appears just to the right of
the track header label (Audio 1, Audio 2, etc.). A single speaker is mono,
a double speaker is stereo, and "5.1" is displayed for 5.1. You can add
tracks manually by right-clicking the header area and selecting Add
Tracks, or going to Sequence > Add Tracks.
It sounds like you're working with media with various audio assignments;
the Project Panel display will tell you how many channels are in your
source clips if you don't know for sure. Once you know that, you can
control where your clips go when you attempt to add them to a sequence.
