Jerk/Burp every 2-3 secs

[andy55]

I was running GForceGold 268 without problem with WMP9 and i-Tunes
for Windows on my WinXP SP1 PC.
After upgrading to version 270, I have jerky playback with WMP9. It doesn't break down or anything, even shows album covers and all - but, as I said, jerky visualization!
I-Tunes is running great.
What could be the problem? [/quote

For everybody experiencing the same problem, I can answer my own question now: I found out, that actually Norton Anti Virus is causing the jerky playback in Windows Media Player (as well as in the standalone version, I discovered since)! I-Tunes is, as I said not affected! As soon as Norton Anti Virus Autoprotect is been disabled, visualisation switches to smooth playback! Very strange! ???
Maybe someone can explain this to me!?!

Setting anti-virus background processes so that they don't continuously scan can do the trick (as you've explained). In place of continuous scanning, just have your anti-virus software do a daily scan at 2 or 3 AM or something.

Aside from this, I would very much like to look into this more are see if there's anything I can do (the key piece of information being that this all started with G-Force 2.7). Unfortunately, if I can't reproduce the problem here locally, there's no way I can examine what's going on (I have yet to see this with my own eyes--I just hear about it). So, if you live in the Boston or New York City area, let me know and I may just make a house call (no joke!)

I had something similar. I still would have if I had not ensured that my player (originally WMP, now JRMC) runs at "above normal" priority.

As a test, use the Task Manager to increase the process's priority group to "Above Normal". This won't cause any problems elsewhere, but in my case smooths out the visualizations.

BTW: W2K, XP and NT have an interesting treatment of thread scheduling. Every three seconds every thread gets a substantial priority boost which can wreak havok on real-time responses.

I hope this helps

After reading some Reply's to this Stutter problem, I tried disabling some of my AntiVirus Software. Guess what? It stopped!!!! I disabled CounterSpy which runs in the background. The stuttering stopped! I then re-initiated CounerSpy and the stuttering started again. This is great news! I don't know why I didn't think of it before. Pass the word around.

Hope this helps!
