So when I want to watch Netflix/Hulu+ or Vudo I set my DD-WRT router to a Astrill US VPN. And when somebody wants to play games locally (NZ), or watch vidzone (NZ only), or TVNZ on demand (NZ only), and now also Quickflix(NZ only). I simply connect to the NZ VPN. No setup changes on the PS3.
Yes I could use unblock-us, but then disabling/enabling dns settings every time on the router (or manually on the Ps3) is going to be a bit of a pain. Not sure if anybody has a solution for this? I have tried out unblock-us and speeds are marginally better. But I have no problems watching Netflix 720p HD over the VPN either.
The Asrill software is great and integrates well with DD-WRT. I am yet to see a better solution. But open to suggestions as my Astrill VPN is up for renewal in a few weeks.
