I dont think Windows movies maker can encode ur AVI files to WMV files, it just is a a basic video creating/editing software introduced by Microsoft. It contains features such as effects, transitions, titles/credits, audio track, timeline narration, and Auto Movie. It can only accept video files in format AVI, WMV, MPEG, etc. So, if you wanna encode AVI to WMV, check out this free video file converter . It’s pretty good at convert various video format.
