Is there such a thing as...


an adapter that goes from HDMI to component?
Convert?fit=crop&h=128&policy=eyjlehbpcnkioje0otu2mdmxodasimnhbgwiolsicmvhzcisimnvbnzlcnqixx0%3d&rotate=exif&signature=9d689e6467fefe05c8e8d3f710485d009f9f75ffbb3bbe613546192b59c7cb80&w=128tabl10s
I can't say for sure, but I doubt it--it would have to be able to cross convert from Digital to Analog signal which would generally require some electronics to handle that processing.
This should help:

Do a search for visionfc4. It's pricey but it is suppose to do what you want.
Technically, these things are called transcoders, I think, not adapters because of what Kjweisner said. Run a search on HDMI-component transcoder. There are some available on ebay
but remember, since its an active device, you will need to get one w the proper input and output. Most of these are not 2 way devices. Key digital is a good manufacturer.
Go to HDfury.com

I have not tried thi but there are some that think it is great as it will...get past...the handshake issues.
The HDfury2 looks interesting. I wonder if it will decode HBO encryption?
It is my understanding that HDFury is a way to get an RGB Device to play DVDs, etc. that are handshake dependent. They have a FAC page. Try asking there...
