I've done the registry hack to get itv hd. I can get picture, but no audio on channel 130 windows 7 media center (compro s350 pci card). Well I get audio for about one second after I switch from one channel to 130. I also have itv hd on channel 4756. If I switch from a freeview channel to 130 I get black screen and no audio. I have to go from BBC HD to 130 to get the picture, but still get no audio. Can anyone help?
