Your best bet is probably to use a browser plugin like ad block plus to disable video embeds (and, if you'd like, most ads as well). It likely won't block the content automatically (it only blocks known ads automatically out of the box) - you'll have to tell it to block those videos after you install it, but once you tell it to you can have it block all video embeds, or just embeds on WP.
Your other option would be to potentially block all flash objects from loading in your browser - but that would inadvertently affect other sites as well as WP.
