MacBook Pro occasionally freezing since bought

I bought my MacBook Pro in August, and ever since I got it, with both Leopard and Snow Leopard, I have had a problem where an app would freeze, typically Safari or iTunes, but could be any app, I would try to go to the dock to force quit it, and the Dock would freeze, went to right side of menu bar and that would freeze. About 10-15 seconds later it would resume normally.

Interestingly, if it freezes as I am playing a flash video on the web, the audio would continue but the video would stop, and when it continued it would fast forward to the current point. Also, once I was printing to a USB HP AIO, and when my computer froze the printer would freeze, when my computer continued the printer continued.

The last time it froze, I went to Console afterwards and found a bunch of these errors:

When I got this Mac, I did a Migration from Time Capsule, but for some reason it could not finish and I had to move over a lot of apps with drag and drop.

Have you done any maintenance?
Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk.
You could have some directory corruption. Let us know what errors Disk Utility reports and if DU was able to repair them.
After that Repair Permissions.

Dale,

Thank you for your reply.

Did not receive any errors doing a disk repair.

Here is the Repair Permissions log:
Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent" has been modified and will not be repaired.
Permissions differ on "Library/Application Support/Apple/ParentalControls", should be drwxrwxr-x , they are drwxr-xr-x .
Repaired "Library/Application Support/Apple/ParentalControls".
Permissions differ on "Library/Application Support/Apple/ParentalControls/ALRHelperJobs", should be drwxrwxr-x , they are drwxr-xr-x .
Repaired "Library/Application Support/Apple/ParentalControls/ALRHelperJobs".
Warning: SUID file "System/Library/PrivateFrameworks/DesktopServicesPriv.framework/Versions/A/Reso urces/Locum" has been modified and will not be repaired.

Strangely, I ran Repair Disk Permissions right after I did the Repair Disk on the Install Disc, and then I re-ran it trying to get the "Warning: SUID file..." so I could put it in this message, but was surprised to see that it repaired the Parental Controls files twice.

The problem hasn't occurred since I wrote this. It used to happen a lot more than it does now. I tried a safe boot and deleted the cache a couple weeks ago, which seemed to help in the short run. Lately it only happens once every couple of days, but the days it happens, it usually happens more than a couple of times.

And just to note, I have Mail open in the background 95% of the time. So that means it doesn't just need Mail to be open.

Also, it seems to happen more often at home than elsewhere. At home I typically have it connected to my 24" LED display, and to ethernet, and is the only time when it does a Time Machine backup to my Time Capsule. Wonder if that has something to do with it?
