What a difference a day makes. When I searched yesterday, I could not find anything related to this problem.
I have two receivers, a rxv777 and 577. Both died sometime yesterday. I went straight to vtuner to check if their service is ok.
I don't think it is related to country. Only the new receivers that use airable work. Everything on vtuner.com from Yamaha is dead.
I tried all day yesterday and a few hours today to set up a local server to serve the xmls served by vtuner but there's no documentation available. If they somehow restore the service, I'll capture the traffic to get all the links and file formats. The protocol uses simple xml files.
