My Samsung Digimax A7 digital camera is capable of shooting video footage. The file format is .avi, but I found that my Titanium PowerBook was incapable of playing the video. It is my understanding that QuickTime supports the AVI format, but not all of the codecs associated with it.
When I arrived back home from my vacation, I tried the video on my desktop G4, but still no luck. Then I tried them on my new iMac (Intel). QuickTime was able to view the movies with no problem whatsoever!
[robg adds: This seemed odd to me, so I had veggiedude send me a short demo clip. Sure enough, the clip would not only crash QuickTime Player (7.1) on my G5, it also sent CPU usage to 100% in the Finder when I simply selected the clip. When I moved the file to the Intel mini, it played back perfectly, in both the Finder and QuickTime. In QuickTime, the movie's format is listed as Apple OpenDML JPEG.
I then looked at the /System -> Library -> QuickTime folder on both machines, and found only two differences: ApplePixletVideo is version 1.2.9 on the mini vs. 1.2.5 on the, and QuickTimeUSBVDCDigitizer is version 1.3.6 vs. 1.2. I tried copying these two pieces back to the G5, but it didn't help, so I don't really know why this video works on Intel yet fails on PowerPC.]
