Warning I am an extreme n00b in this subject.

I just got a digital camcorder and I'm just getting my feet wet with the various software programs out there. I understand that there is seperate area in the program for imported Video, Audio, still images, etc. (I'm using ImageMixer, M$ Movie Maker, and I also got a demo of the Ulead program) My question is this -

The video comes off my camera as an .mpg. I import that into the program. However it just comes up as Video. Where is the audio that I recorded at the same time on this track? I understand these programs make it easy to add background music etc but I as a beginner here I'm just trying to get the video and audio from the same movie in together and I don't know why I'm having such a bear of time doing it. It can't be that hard yet I can't figure it out.

Did I explain that well enough? Can someone help me here?

PEACE
