Question
Jumpy/Jerky Audio and Video Playback
Hi all,
I have a problem with audio and video playback whereby every 20 or 30 seconds I get a 2 second slowdown and jumpy music/video in ANY media player.
The added unsual aspect of this is that, I don't believe it is a codec problem, I have reinstalled the players/codecs and changed the codec packs. The AV is fine as long as the wireless network is disconnected.
This leads me to believe some process is accessing the internet or network and causing a spike in CPU usage which causes the jumpy sound. I have used NetLimiter Monitor to look at the process activity and nothing is incoming or outgoing at the time the sound jumps. I am now totally lost as to why the sound is like this and have CPU spikes every 20 seconds or so ONLY when connected to the network.
Thanks in advance, let me know if you need more info.

Well then it seems the wireless is probably the culprit at this point. Do you have another adapter you can try? Or maybe there is a firmware upgrade you could try for your current adapter? It could be from a hardware conflict with another device on the bus, or a lack or power if it's on a USB port. I've seen powered USB devices cause all sorts of problems.
What make/model is this wireless adapter, and how does it connect? USB or PCI? Built in?
Also, is this a laptop?
Firstly, thanks for your input. To answer your questions, Its just a cheap unbranded usb dongle wireless adapter as I am hardwiring things soon. It is running through USB on a desktop PC, it should have enough power as its going direct into the usb port on the motherboard and not through any extension cables.
But what makes this wierd is, If I just disconnect the wireless adapter through software but leave it plugged in an on, it solves the problem (but obviously have no internet) This is why I thought it could be some network traffic communicating with a process to cause the cpu spike and then jump but netlimiter shows no activity at the moment the jumps happen when it is connected to the internet.
I've had devices that would cause one motherboard to flip out, but work fine on another. Most of the time these are things that do not have external power sources, and require power from the 5v connectors on your USB connection. It could just be that the device pulls more when in use (which makes sense) and that one motherboard just handles it better than another.
Regardless of the reason, a new adapter is probably the next logical step. If you're not planning on hardwiring it for a while I've had good luck with the WMP54G series Linksys PCI adapters. If you must use USB though, the WUSB54G is a decent choice as well. Maybe you have another adapter, or know a friend who has one you can use to test with?

Updating Video/Sound/Network card drivers would be my first step after codecs.
Try disabling overlay support in Windows Media Player (if this is what you are using.) This can be found in Tools->Options->Performanc
Also, VLC Player is available at http://www.videolan.org which is free, and has most common codecs built in. It can help you avoid a lot of the headaches of dealing with decoding problems.
