I keep a collection of Captioned videos, but sometimes it’s to much what I like.
To search all know sources of captioned movies, try Captioned Video Search 2
This searches for captioned videos on Vodpod, Overstream, Google Video, YouTube, and subPLY.
Some of my other attempts:
Caption Video Search 1
F Search
[Edit 8/13/2009] Someone has made a “Yahoo Pipes” search
