That said, there are still tons of pieces of gear which have component video HD outputs that work just fine including cable tuners and better media players. It's the cheap stuff that just has component, and current BD players, but it is a pain to deal with and leaves millions upon millions of TVs out in the cold. I accept this as reality, but it's still about the stupidest thing in existence. Component HD looks great and works well and was fairly inexpensive to implement.
Whatever... I would pick up the linked product from Amazon and call it a day. But, the other posters are correct in saying that the HDMI to VGA/5-wire/component 'cables' sold all over are nothing more than a fraudulent scam. They are garbage and you got duped. HDMI is digital, you need analog, there MUST be an active converter between the two. As well, there is HDCP to deal with on many sources, and you must deal with that as well.

It's required by law that cable providers make available cable television tuners with component video HD outputs on them still upon request from users. Call them up and let them know that you want a cable box with component video outputs on it. They are supposed to have these available for at least a few more years.
The Analog Sunset has nothing to do with anything related to the CATV industry, and was part of the AACS fiction of Blu-ray Disc....
I have seen a few cable tuners without component video outputs, but the cable companies still have tuners with component video outputs.
You don't need to buy a fix, you should just be able to get it from your local cable company.
To that end, there is a link on the Brighthouse website on how to hook up to your TV using the component video connections which are on your cable box:

You are jumping through hoops you shouldn't need to jump through.
