No you are not the only one going through this I would say.
I even Reboot my Router to make sure that I am not making this up, but many channels & constant freezing seem to be getting to be a regular event lately.
Missing channels are a server problem, the freezing is man made.... 10 seconds on then 10 seconds off is too much of a coincidence..... jealous competitor or similar.
It was a mess yesterday and it is pretty much the same today. Lots of buffering, freezing and kicking out. As of a few minutes ago, CNN was completely down and MSNBC was a stuttering and freezing stream.
