i'm really interested in investing in a tv tuner card but i'm afraid that i'm going to burn my mobo. i've heard that the cable wire has too much power and someone told me that there is a small connector which should be attached b/w the cable wire and the card which doesn't allow power to enter the card except the channel waves. is there really such a connector/filter available? if so what do they call it? is there anything i can connect to the cable or do something that will help me prevent my mobo from getting burned? btw can anyone give me the details for mediatech dealers in hyderabad? i'm going to buy a comprovideomate pvr card.
