HDMI to RCA convertor.

[dieseljeep]

I was looking for a convertor to use an HDMI output to what they call RCA outputs, which is left and right audio and video. The jacks on many of the older sets and on the modulators.
I saw one on line from China, but didn't know that it would be suitable. I actually bought one from Walmart that looked identical, but for more money.
I figured if it wasn't the right one, I could always return it. I found out that it works really well.
I ordered three one line. It comes with a USB power cable, but that all.
It turns out the Spectrum convertor has a USB power source.
Anyone else have experience with these?
