didn't quite get the answer I was after as I wasn't too clear.
So, I'm wondering if you can get teletext in windows media center when watching a dvb-t broadcast on TV1 & 2? From what I can gather, it does work on dvb-s
I've tried the text button on my remote aswell as going into the 'interactive' options when watching a program. The htpc is connected to the tv via dvi>hdmi (heard that can be an issue with some settop boxes...)
