Well, I dont believe you will get flash to work with the stock Opera period. You will need to get a different Opera build along with Flashlite 3.1. But from my experience I wouldnt bother. It causes problems if not done correctly and it only supports up to flash 8, and most video online now uses flash 10. The only site that seemed to work haf *** was youtube, so really I wouldnt bother if I were you. but I know how it is to feed your curiosity so you can go here :

-Still would reccomend Skyfire browser for your embedded flash needs.
-Or try Web Video Downloader to watch and download web video.
