So I have a 20" Sceptre display with DVI, and I my brother took the HDTV when he moved out (weak, I know) so I decided to buy a 10ft DVI-I to component video cable to try to watch tv on it. I have a DVR/HDTV tuner from time warner that I plan on plugging this into to get it to work. Anyone know if it should work or not?
