If Tube Toolbox is only gathering about 40 pages of results when you set the "Max Pages to Gather" to something greater than 40, read the example below. If you are having a different problem, look at the bottom of this post....
EXAMPLEIf you browser to the subscribers of the user "TietHealth" (http://www.youtube.com/profile?user=diethealth&view=subscribers), you will notice that the user has
19789 subscribers. If you try to gather all of the subscribers, Tube Toolbox will only gather about 1,033.
The reason for this is that YouTube will not let you view past the 42nd or 43rd page of someone's subscribers. If you keep clicking 'Next' all the way until you get to the 43rd page, you will notice that you can't go any further. This probably has something to do with YouTube trying to limit the load on their servers but unfortunately there is no way to get around it as long as YouTube keeps limiting us.
