I just upgraded from 10.4.6 to 10.4.8 using the new JaS DVD. I reinstalled quicktime 7.1.3 from Software Update and also installed Perian.
Now when I play videos in quicktime, vlc, niceplayer, etc. the audio gets all choppy and out of sync with the video. Also, if say Adium or Mail makes a sound, it interrupts any videos or music playing and stutters a few times before the music or video sound comes stuttering back.
Any ideas? If this can't be fixed I'm probably heading back to 10.4.6.

Try deleting AppleHWSensor.kext and delete the Extensions.mkext and Extensions.kextcache before rebooting.

Nope, deleted that kext and the cache files, rebooted, and it's still choppy in every app. Any other possibilities?

If processor has HT, try disabling it or use cpus=1 at boot.

The Pentium 4 506 prescott chip is a single core without any hyperthreading.

Go to Utilities folder -> Console.
Click Logs in toolbar and look at system.log and console.log for unusual activity like continuous errors or some process repeating over and over.

What's the fsb? Are you using auto detection kernel?

All of the errors in console.log deal with Sogudi or a missing Toast contextual menu. System.log has one error: "Dec 6 03:15:13 Prescott cp: error processing extended attributes: Operation not permitted"
The P4 506 Prescott has a 533MHz frontside bus.
And I'm not sure what the auto detection kernel is.

Auto-detection: early versions of new 8.8.1 required that you set a bus frequency at boot in order to run well. This could be your problem. Newer kernels detect this frequency automatically. To update the kernel, see my signature 10.4.8 link. To set your FSB at boot:
QUOTE
When using the Semthex kernel, you may need to set your FSB frequency. It is set to 200 by default.
At boot, type: fsb=xxx (where xxx is a number like 133, 166 or 200)
fsb is a frequency
fsb (freq) = fsb (speed) / 4
Find your fsb (speed) in your BIOS or:
(OSX) System Profiler -> Hardware -> Bus Speed (fsb speed)
(Win) PC Wizard -> Mainboard -> Chipset -> fsb (speed) and fsb (freq) are both avail
Remember to divide the speed by 4. If your FSB (speed) is 667, then your FSB (freq) = 166 because 667/4 = 166
At boot, type fsb=166 (using your value) or put the fsb in your boot.plist under Kernel Flags:
<key>Kernel Flags</key>
<string>cpus=1 fsb=166</string>
(for purists, both FSB numbers are really frequencies - I chose a different name to differentiate them)

I used the manual method to install the mifki kernel from the 10.4.8 DVD and have the same issues. Which version would you recommend?

Forget it, I'm going back to 10.4.6 for now, since I really need a functional Mac. I can't wait til I can replace the iBook I busted in my bike wreck with another real Mac.

Latest Semthex using one of the two installers or manually.

According to XBench, I got a 74 in 10.4.6 and 117 in 10.4.8, but everything in 10.4.6 is snappier (not to mention it works at all).
