Will pci t.v. tuner cards work for "Direct t.v." satalite? - vcr dvr a good read and a handy reference

Direct TV said no. and other forums that I seem to read the experts agree. An LCD screen. Monitor can play, but can not grab a PC?
Even a home VCR or DVR can record TV, "live" with the Table A / R + V + WI "S" cable. If this is the only way to get a disc?
