Video files are messing up

Just recently, my video files have started messing up. Files that I have watched before with no problem, are now becoming blotchy. A large group of pixels will freeze or will become discolored. Anyone else having this problem?

I have a projector so its not the pixels going on my TV. Its the same pixels during the video file everytime I watch it. Also I don’t have this problem while watching cable TV so I know its a hub or a file issue.

I’m leaving the forum. I’ve gone through 4 hubs in just a few months. I love the idea, the themes here are great, but the problems I’ve had are too much than they’re worth. Bye
