He's talking about the Messenger Plus! Live
scripts database
however, I don't think there is anything in there to do with the gifs created by WLM.
I've not tried it myself, as I just create GIFs using photoshop.....but if you've figured out that it's a zipped format and you want the GIF itself then have you tried opening the DT2 file with WinRAR or WinZip and extracting the file that way?
It may be that it isn't possible to get the gif out of this format
