If anyone is considering buying Freeview equipment, I would recommend staying away from supermarket brands. Sony, Panasonic, LG and Samsung are broadly working towards making all of their most recent TVs compatible with streamed channels, Connected Red Button and catch up TV.
It is tough for those who got 2010-2012 Freeview HD devices (with the exception of TVonics for streamed channels), as these additional functions will generally not be supported by any brand, and the cheaper brands don't seem to be bothered about providing updates to make the streamed services work properly.
