how do i find the flash / swf video file ?

[vhelp]

xp home
opera 12.12.1707

sometimes i want to download the video playing inside one of the 'ad feedback' on imdb. they are usually on the right-side of the webpage. i think these are .swf files, but not sure. anyway. i searched the around the webpage source text file (via right-click, source) and Inspect Element (via right-click, inspect element) but i can't seem to find the actual file. not sure what i really should be looking for. and i also went into Opera's cache folders (at least they still provide something to view) but i still can't find the particular video that was playing.

is there another way of pulling these the actual video that is playing in those ads ? or do i have to resort to screen capture ?
