have you modified any of the definitions in any way or added any addtional ones? Can you deactivate them all except for one at a time, edit and save the post to see if it is one of your items that is causing this to happen?

@Danny: There is an additional setting that taks an optional regexp to extract the embed code from the destination page. In the next version, yahoo and dailymotion comes with the package so you can easily see there how it works. I have also implimented the ability to do a page extraction on a per item basis. The page extraction AND the resolve URL setting must be active in order to extract the embed code from a page (in this case yahoo and dailymotion).
