I ended up here:
http://downloads.ddigest.com/software/download.php?sid=1089&ssid=0&did=5&rid=178216 ..then clicked the download button and it's downloading. (This is the "mega codec pack" - the one that has the most codecs in it.

Perhaps your whole problem is that you have mailware or something on your machine eating up all your resources - or some sort of Virus. I would run a full scan and try something like spybot search and destroy to get ride of all the mailware/spyware.

>>>What do you mean by installing different codecs? Where should I get it?
>>
>>codecs are programs that windows uses to decode audio/video - bad codec can result in bad audio or video.

>>Al posted a link that had some links to codec packs - I've used this one in the past with good results:

>>The webex support site did say this:
>>Q. How can I improve the quality of the audio when using local recording?
>>
>>A. If audio quality is poor or if there is no audio, make sure that:
>>You used the WebEx Audio Setup Wizard to test your volume.
>>If you are recording audio from a source other than a microphone, start the recorder and select the correct recording source.
>>If you hear “clicks and clacks” during playback, you may be using an older version of the WebEx Player. Re-install the player on your computer and try again.
>>
>>Q. What audio compression and sampling rates does WebEx support? Which ones should I use?
>>
>>A. WebEx supports the following audio recording formats:
>>
>>G.723 (8 kHz) This is the default setting; it is optimized for streaming over the Internet.
>>PCM (8 kHz, 22 kHz, 44 kHz) This results in higher audio quality but much larger file sizes. This is recommended only for recordings that you distribute on a CD-ROM.
>>
>>..so it looks like you should try to get codecs for G.723 (8 kHz)
