I could pretty much guarantee Spark will give you the massive run around for ever and ever and ever...
As it was Telecom / Spark who were selling these in NZ, wouldn't it make sense for them to try and get the license for say 5 years, to keep the EPG going just for NZers? The problem is we were never told that there was only a 10 year license on the boxes being able to get the EPG, and by the time these boxes got to NZ, that would have only been 7-8 years left on the license. They were still selling them up to 4-5 years ago as well, and in the end they were including them at no additional cost if you signed up to a 12 month contract broadband connection.
If spark got lightbox to run it, they could put netflix and lightbox on it, and maybe even bring in the new generation boxes, and distribute them in proper bricks and mortar retailers this time?
