iTunes locking up iMac

So, I've been fighting with my iMac for about a month now. Issue is that iTunes and/or the Finder locks up. Applications that I already have open seem to continue to function but if I leave my iMac on and come back to it, iTunes either won't open (icon just bounces in the Dock and it never opens) or it is unresponsive and I have to force quit it. At this point I also cannot restart or shutdown my mac, when I choose either option from the Apple menu, the Dock hides and my desktop clears as the os is preparing the mac for the shutdown/restart but then it hangs with the spinning pinwheel and I have no choice but to do a hard boot with the power button.


I do use EyeTV to watch/record TV on my mac. I do export some recording into iTunes - I rarely get even 1 show to export successfully before iTunes is hung and I have to do a hard reboot and try again.


I have not installed any new software recently. Steps I have taken to try to fix the issue (not in any particular order):

1) Unplugged power cord to reset SMC

2) Reset NVRAM/PRAM

3) Repaired Permissions using Disk Utility

4) Verified with Disk Utility both the internal MacHD and external 2TB hard drive (USB 2.0/3.0) - both check out as OK.

4) Zero-formatted MacHD, reinstalled snow leopard (retail), downloaded 10.6.8 combo update, installed that, rebooted, repaired permissions, rebooted. Re-installed applications (including iTunes) (did NOT restore them or any Library files from backups).

5) I've also tried "removing" iTunes and reinstalling (but I'm not sure how successful I was at finding and removing all iTunes components).


I just don't understand what could be causing this "hanging" behavior with iTunes. The mac and other applications seem to run fine until iTunes hangs. Then I have to do the hard boot with power button.


Specs:

Aluminum iMac (20" mid-2007; model ID: iMac7,1)

Intel Core-2-Duo processor; 2GB RAM

Mac OS 10.6.8 (Updated from 10.6.3 retail package install by Combo Update download/install)

iTunes 10.6.1 (downloaded and installed directly from Apple.com

(iTunes library is on the external hard drive (2TB Seagate Go Flex) as the iTunes Media folder is too big to be on the MacHD)

In Control Panel: Energy Saver: I have hard drives set to never sleep, Computer set to never sleep, Display set to sleep after 2 hours (screen saver doesn't turn on for 1hr45min).


Here's a snippet of recent Console log errors:

I'm having a very similar problem, which started relatively recently (within the last several weeks). When I start iTunes, the whole system and any running applications slow to a crawl. Although not locked up altogether, the system takes 30 seconds to a couple of minutes to respond to any mouse click or key stroke, and any display updates are stalled until the very short open window for other processes opens up (briefly!) again. With patience, I can switch the input focus to iTunes and Cmd-Q to close it, after which everything returns to normal.


Mac OS 10.7.4

iTunes 10.6.3 (25)


iTunes is unusable, as is the rest of the system while iTunes is running.

I have a Late 2011 iMac 27" - it was locking up 2-3 times per day. It would totally freeze while I was using it, or just a black screen when I tried to wake it up. Sometimes, once per week, it would get a freeze with a strange sound coming out of the speakers.


I removed to items and I've been lockup free for 2 weeks straight: I removed Perian (Preference Pane) and uninstalled Flip4Mac. I should have gotten rid of one at a time, but I don't need either right now.
