I just picked up a Voom Receiver.I am installing a HDTV antenna and running the coaxle cable to the receiver.I read in a Voom Setup, that if your not using a POWERED ANTENNA, then you do not need the Module on the back of the unit.Is that a OTA Module or a Diplelor? Anyway, how do I take that off? It is on pretty tight and no screws to unfasten. If I am wrong, please let me know.I also went to my HDTV ready TV, plugged in Componet Video cables, went to Video on the TV and it says it is 'not supported'.Do I have to use DVI cable to get HDTV signals?Any help would be greatly appreciated.
