For all those experiencing video pauses with Rumble, I would like to suggest input the following:

I don't think, at least not what I have seen today, that the buffering issue is related to the Website.

1. I have had Rumble running all day, and have not seen one single pause, or disruption.
2. I am connected via cable to router, not wireless. You may want to see if this changes you pause/buffering condition.

Update: I disconnected my eithernet interface cable, and went wireless, and I am still not getting buffering, but I am working right next to my wireless router.

If I move further away from my router, I probably will get some buffering. I was seeing this occasionally when watching from my bed last night.

Try moving closer to you router, and see if condition changes. If it does not, you might want to try doing a cold reset of you router. This thinking is to do something that may result in the buffering condition changing.
