A demonstration that my equipment was working and I was able to upload, so the issue is/was with Rumble. First day without a show in over a 1000 days. Think about that. No fun allowed!
A continuation of the previous discussion hopefully without idiocy in the chat.
SHOW NOTE: I've tried a few adjustments to perhaps prevent the jumping and buffering, though I don't know why I would have to do it, since things have been fine for the last several hundred shows. We'll see tomorrow.
