One really annoying thing using digital still cameras for video editing is that Windows Movie Maker can't open the source footage. Some cameras record in MPEG-4 format or MOV, like Flip video, Sony Webbie, Sony Bloogie, Kodak Zi8, etc, but Windows Movie Maker can only work with files such as AVI, WMV, MPEG-1, ASF, WMA, WAV, MP3.
