Used Unotelly in the past but have recently moved to Dns4Me - everything works as expected except subtitles are still coming through even though I have set them to be blocked.
After trying all the usual things such as rebooting, switching to other regions etc., I raised a support ticket this morning. The answer I received was :
"Unfortunately Netflix made some changes a while back that made our subtitle blocker redundant."
So basically the subtitle blocker does not work - might be nice if there was a note on the services page about that!
Anyway, does anyone have a way around this on an AppleTV 3rd generation?
