New you tube upoads from my subscriptions not appearing in my account

I know there have been several threads on you tube censoring, but I did a search and did not see this question answered. So I am asking you guys for help.
I subscribe to over 150 channels and in the past I would get so many new videos a day I couldn't watch them all. Now it is just the same vids from the same channels over and over. So I have been checking some of my regular "good channels"and they are uploading everyday, but I am not getting the uploads in my subscriptions??? Why would this be?? I should be getting all uploaded vids from all those I subscribe to. Of course all the news channels are getting directly in my subscriptions, but the good stuff nada. Please let me know what you guys think?? I know its probably youtube censoring, but I still want you opinion. I haven't posted any channels as I am unsure if that would be against ATS policy, but if not I will gladly list some. Most do with UFO's etc.
