I just make a happy discovery: Flash stores videos it’s currently playing (eg. from YouTube, Megavideo, etc) within the /private/var/folders/.../ area.
Access it by hitting Cmd-Shift-G in Finder, typing in /private/var/folders and hitting enter, then navigate around until you see something like a TemporaryItems folder – within will be a file called something like FlashTmp0, which is the .flv file.
Copy it somewhere and rename it, and it’ll play in VLC or any other player that supports the format (like Quicktime etc with Perian installed).
You can also see the direct link to the .flv in the Safari menu bar
“Windows” >> “Activity”! Check the biggest file…
Great work with Elegant Grunge!
