After viewing your DVB log, MP is properly scanning for channels. I see no error in MP, therefore it must be in your reception. I don't know if you can get an ATSC signal on another TV in your house, but ATSC reception is a little different than NTSC. It is a UHF signal, and needs a UHF antenna. The "bowtie" antenna is popular. My rooftop antenna is actually eight bowtie antennas in one large antenna.
