yep, installing this cause my saf to quit when i simply log apple.com (when the quicktime iphone animation try to use the component). putting the perian component out of /lib/quicktime resolve the prob, in my case. so i just put again the 0.5 comp again to solve this. no more :) hope you can resolve, thank you 4 modding FrontRow.
