i just got a casio exilim Z850. i get blank frames in iphoto when i import. I've head that an app called VLC will playback the .avi files when i transfer them to my hard drive. where do i find it? i've been resisting the blackhole of codecs, converters, etc. but that won't get me watching my camera's video output. if someone would please walk me thru setting up my mini to read the .avi file. (even the casio 1.1 converter doesn't play my video well) also do you know why anyone would update the camera's software - casio offers a video upgrade on their website.
