Since many, many kernel releases my Hauppauge WinTV HVR-1400 doesn't work anymore, and nobody feels responsible to fix it. The code to get it work is still in there, it's only commented out. My patch to enable it was rejected, because somebody had fear that it could break other cards. So here is a new patch, that allows you to select the frequency adjustment code by a module parameter. Default is the old code, so it can't break anything.
