@Mickkie - your TV is using MHEG to pull the digital equivalent of teletext. It's a licensed product available on official Freeview and Freesat receivers. linux boxes generally don't support MHEG unless you purchase a licensed add-on. The idea behind HbbTV is that it is open source and therefore free from the same licensing restrictions. I've used it on my MBTwin on various German satellite stations. I don't see HbbTV available as a plug-in for my GB Quad Plus, though. I'll check it out on my HD51 in the morning.
