If you are trying to get Read nodes, you can make your list smaller with:
def CallbackTest():
allNodes = nuke.allNodes(filter='Read', recurseGroups=True)
for n in allNodes:
path = "./User/movies/videofile.mov"
n['file'].setValue(path)
you already found the node, so you can just use 'n' instead of nuke.thisNode(),
which is probably just going to loop the error on the root.
