Question regarding YouTube Channel and Population of Timeline.

A small question for the boss man if I might. 
When PTVL creates a Channel from a YouTube Playlist, Is there a limit to the number of Programs then PTVL loads from the Youtube channel or does it just load a list of all programs and continually add them to the channel?
The reason I ask, As I have made a whole lot of YouTube Channels, to get around the random problem. I have noticed on one channel, Which is a Channel filled with Classic Movie Previews, that I have about 10 or 20 Entries, that play over and over from a Channel of about 150.
PTVL seems to just grab the first 10 or 20, I cant remember the exact figure, and repeat them in a loop. 
Is there somewhere to increase this number, or is this a problem with the youtube addon, or something else.
TIA
