I use iMac and have just changed from iPhoto to Aperture 3 but now all my home videos are reading Unsupported Video Format (MPEG1 Muxed) any ideas?
My videos in Aperture are saying 'unsupported video format MPEG1 Muxed ..... what have I done and how can I become un-Muxed?
iMac (21.5-inch Mid 2011), Mac OS X (10.7.3), using Aperture 3
