ive got a problem with my xp media centre pc, recently i updated the freeview box attached to it to add new channels, (which still works fine) then updated the media centre in tv settings, now i get no sound when trying to watch Tv, i can see the picture fine.
Ive checked the cables to see if they have come loose, checked to see if i can play music which i can so the sound is working but not for the TV part?

when i choose Setup TV signal from settings menu-it doesnt find the channels when i go through the menu that way-although im not sure if thats ever worked.

ive spent hours and hours on this problem trying to re-scan for channels and i just seem to be going round in circles with it!

Any help really appreciated!
