Heat issue

I don't know what's going on but when I try to stream anything on Heat VOD it will play for about 5 minutes and then the video just freezes. I will try to go back a few minutes and it will play until that same time. I have tried just letting it be and pausing it and it does not ever start playing again. I have tried to fast forward and it won't play.

I have tried some of the same shows on Heat Ultra and while I am not having the same issue, I am getting a message from shows on Hulu that I have noticed so far saying that the source does not exist.
