Adam has an older Mitsubishi HD TV that he really loves. It still works fine, but he needs an over the air converter that won't burn out over time and has component out. Leo says that Silicon Dust's HD Home Run or Channel Master's DVR are his best options. But Adam may have to get an HDMI to a Component converter for the video out. But using one of those will open up other digital tuners as well. The nice thing about the HD HomeRun though, is that he can watch TV anywhere in the house by connecting a Roku device and using the HD HomeRun app.
Lance wants to listen to alternative audio on his TV while watching video. Leo says that if you're connected via HDMI, the TV will play both automatically. The only real option may be your AV receiver, but that's likely going to do the same thing. Component out might work.
Greg has a DVD/VCR combo, but it only plays in black and white. Leo says that the likely culprit is a bad composite cable (red, white, yellow). So he should replace that. They're pretty cheap. ScooterX in the chatroom says that in the memo of the DVD player, there's a setting that could be affecting it. The TV may be using the same jacks for component as it does for composite. He should check his menu settings. TomsGuide has information on how to do that.
Joey inherited an LCD TV and he needs an adapter to plug in from his old coax cable box. Leo says that coax is an analog connector designed largely for over the air antennas, rather than digital, which is what HDMI or DVI is. Leo says it's going to cost Joey more to get a Coax to DVI converter than it would just to get a new cable box. Then he can get an inexpensive HDMI to DVI adapter. He'll also need a separate sound cable. Since Joey also has component, another option is to go from Component to DVI. That's an inexpensive option as well. But then he could end up with sync issues.
How can Robert move from component to HDMI? Leo says that component is the last bastion of analog and he'll need a digitizing box to move to the digital signal of HDMI. But that's only half the problem. Robert may have an issue with copy protection as well with HDCP. There could also be sync issues.
