12.1 Wildly incorrect audio and video sync with xvidcap/recordmydesktop etc.

Trying to produce some screencasts but the resulting video has the audio playing by what sounds at least double speed. This is the same with xvidcap, recordmydesktop and using the screencast-o-matic (http://www.screencast-o-matic.com) service.

Any help would be greatly appreciated.

Thanks.

oldcpu posted a ffmpeg alternative for desktop recording here. Perhaps it will help you.

You do have your multimedia set up according to the multimedia guide, do you?
