i am using dvb-t card on my computer since 2009 without any problems but since last night it has been pixelating on mediaworks channels its random when it will happen but seem it be within 2mins it will pixalate but the audio is fine

i thought it was media player classic problem so i tried vlc player i get the same problem so i reinstalled the drivers for the card that did work also updated my graphics card driver still get the problem

could this be a problem on mediaworks end?

any help would be great
