Voice Thread and Movie Maker

I recently have been introduced to Voice Thread and Movie Maker. While I was playing around and experiementing, I discovered that I had trouble importing video files. After much searching, I found out that my Sony digital camera saves the videos as a mpg file, which is not compatible to Windows Movie Maker (I assume this is the same problem with Voice Thread-if anyone can confirm this, please let me know).

I tried downloading several different conversion software and finally settled on AVS conversion.
After many hours, it finally worked. I was able to convert the mpg file into a WMV file and complete the presentation.
