The subject should do it...

; Google Video (*.gvi) to DivX (*.divX) converter
; Removes the Google header and changes the file extension
; to avoid playback issues with various video players
; Warning: more checks should be implemented
; On the other side, it's only an example...
; ...with a lot of IF's

What i do is find a movie on google that i want to download then i follow these steps:

1). Click the download link on the movie's page.
2). Open the downloaded *.gvp file in a text editor.
3). Copy the url listed in the file.
4). paste into a browser address bar and hit enter.
5). download full original movie with no google flash compression.

sometimes the downloaded movie has headers that are missing but it is otherwise ok. You can use SUPER to convert it to whatever format you like.
