I just noticed that someone found this blog using the following search string:
iphoto powershot sd750 trouble importing
If that person is still reading, I recently had a problem importing AVI videos from my camera into iPhoto too. Every time I tried to import the videos, the iPhoto application would crash. Found the following item on the MacFixitforums.com:i might have found a solution: i deleted AviImporter-r7 (Intel).component from /library/quicktime and uninstalled flip4mac. i dont know which of the two caused the problem, but now i can import videos from my camera into iphoto.
It turned out that AviImporter was the culprit in my case. I deleted all the AviImporter stuff from the library, and the problem was solved. Movies imported just fine again.
I also noticed that I’m still getting a lot of hits from the search string “macbook flickering screen” or similar searches. Amazing that there are STILL bad Macbooks being sold out there. It has been several months since I got mine and posted about the problem on this blog. To those people, I can only say take/send the thing back — there are good ones out there.
