Now only one person can stream

Looks like PlayOn is still streaming it, even after rebooting Windows. So until Comcast removes it, only one person gets to watch.

Use the Chrome extension, then you can view anything. No casting, because you have to be on the same network, that is the same IP range.

PlayOn will sort of work without that, but you have to punch a hole in your firewall. Why does casting require the same network? Guess I should put Windows on the other VLAN. Then I have to punch a hole to give it access to my share. And change the config, to allow it. To much work.
