Well, I gave up on sonar video, however i fugured out an easy free way to do it. I loaded the video and audio into sonar and matched the audio to the video's audio to sync it up. Then I extended the audio to "zero". export the audio as a brodcast wave. did nothing with the video.
opened my freebie version of Windows Live Movie Maker (6.0), imported the video clip and then imported my broacast wave, "published" to my computer. This combined the audio with the video. (you need to mute the video's audio). Then I opened that new video and was able to edit the beginning and end etc. you can check out my vid.
would love to hear feedback on the mix, but the video is nothing special, just tracking vocals, was just for fun. was from my iPhone. My fist time ever doing anything with video.
