I've just downloaded the "Windows Live Movie Maker" for Windows 7.
My MP4 video had no issues. However, Movie Maker won't accept my pre-recorded MP3 audio - what's up with that? It was recorded on XP then put on a USB stick and brought to my Win 7 PC. Would that effect it? How can I fix it?
If not, how can I get my MP3 working? I never thought MP3 would be an issue.
