Can someone help? I've been trying to connect my dtv converter box with my dvd/vcr combo with no success. Does anyone know how to do that? I've been doing searches on the internet and there are several websites that tell you how to connect to a vcr or two both a vcr and dvd player, not a combo. There's talk about needing an RF splitter and/or an RF modulator. Not sure that I really need all that. Any help would be appreciated. Thanks!
