1 Windows Media Centre 2005 setup does not allow more then 2 TV cards to be used at any one time, even though it recognises all the TV cards present in your Home Theatre PC. There is a registry setting that can be used to enable each additional TV card, so that, they can be used transparently with in Windows Media Centre 2005. When three TV cards are enabled, you can record two channels and watch a third channel or you can record three channels simultaneously. Recording conflicts simply become a thing of the past!
