1. What do you mean by "running QuickTime". Do you mean just playing audio or video in QuickTime Player? Can you play video in other OS X apps that use QuickTime, like iTunes and Finder Preview?
When I watch xvid or mkv videos, it's not consistent pattern, but it seems to only happen when I play videos while multitasking and doing other tasks. I have tried using vlc and it does not give me kernel panics, at least in the last 3 days of watching videos and doing other tasks on the computer.
2. Test the problem in a brand new user account. This will pinpoint whether it is a system-wide issue, or a user issue. If it's a user issue, it'll be caused by something in your user Library folder, like a cache, corrupt preference or Login Item that's conflicting.
Thanks for the tip. I will try that.
3. Have you installed any software that gets its hooks into the system? hardware drivers, keyboard macros, Audio Hijack, Little Snitch, that kind of thing?
I haven't installed any of the above, but I do have other menubar items going (e.g. dropbox, fantastical, moom, sparrow, teamviewer).
4. Read the Kernel Panic logs. You can find them in the Console utility. It may look like gobbledygook, but it may constantly mention something like IOUSB, or Audio, or some particular bit of software.
Here is an excerpt of my log:

5. RAID 0? Why? Minimal performance gain for twice the failure rate.
[/QUOTE]
I thought RAID0 with double performance of write and read would be worth it. I've had zero issues with my 2011 raid0 samsung 830 drives. Not worth it?
