Connect cable box to home theater system to connect to a computer monitor?

Kip Ockenfels: hdmi FROM wat to the computer moniter?u said the cable box is not hd.anyway if i assume u talking about the cable box going hdmi to the moniter and coax to the receiver that may pose a clash since both coax and hdmi are designed to output sound and picture both.u can try it.but incase u run into quality problems forget about the hdmi and coaxial out.go rca audio 'out'(red and white)on the cable box to the audio 'in' on the home theater system.and go component 'out'(red blue and green) on the cable box to the component 'in' computer monitorP.S.: u may wana try audio out instead of coaxial out to the home theater system along with hdmi to the monitor.again it is most likely not to be compatible...Show more

Willetta Munhall: You NEED a video capture card period. EDIT: And DONT waste your money on a TV tuner card especially if you have cable or satellite! You CANT tune with the card anyway.
