Okay. I can help you with the season 4 clip you asked. You can found it here:
http://www.savefile.com/files/3154951 But for the pilote clip, I have it on CD, but I can't copy it or send it. It doesn't work, I don't know why. Sorry.
If you need it only for the image, I have it in French too, and I can post the french clip. But if you need the english track, I can't help you, sorry. Except if you answer quickly to tell me you don't have use of the french clip, I will post it in a little while (time for me to cut it and upload it).
