I've downloaded & installed the trial version of this software and I'm having trouble with imported media.

I have some .avi video files that where created with a Canon Powershot S1 IS. They play just fine in various media players and I was able to use them with the trial version of Ulead to create a short movie. However, after importing them into Vegas MSP, there is only audio. The video doesn't seem to be there anymore & when I add the file to the timeline it will only go into the audio track.

Any ideas?
