Quicktime Observation Before upgrading my Mac mini to 10.6, I had installed Quicktime Pro 7. I had set up Quicktime 7 Pro to be the default app to open my .m4v handbrake video files rather than iTunes. I just was testing some movies that I encoded last night before the 10.6 upgrade, which I did this morning. Double clicking the .m4v file opened it in Quicktime 7 not Quicktime X. I looked in the applications folder to see if Quicktime 7 was still there but it wasn't. A quick Spotlight search and I found that Quicktime 7 (at least the Pro version) was moved to the utilities folder. Conclusion: If you do a 10.6 upgrade install, and you have Quicktime 7 Pro, you don't have to install it from the 10.6 disc, it's just been moved to your utilities folder.
