It has always been one of the big "THOU SHALT NOT"s of HDMI that modern HD content can't go to an analog channel, hence HDCP fails when trying to use streaming boxes etc through analog converters. Therefore official HDCP compliant devices that do that, don't exist. Probably unofficial ones do, but they're the kind of thing that might get blocked at customs if ordering from overseas.

Didn't that only apply to "high definition" analog signals, such as YPbPr component video and VGA? Weren't converters to standard definition (and lower quality) analog formats (basically anything 480i and lower, including S-Video) exempted from that rule?

Anyway, if you can't find any HDCP-compatible HDMI-to-S-Video converters, you could try looking for an HDCP stripper and run the HDMI signal through that first. It would require two boxes instead of one, but it should work.

That would actually be excellent because I could use my existing setup.

Most HDMI to composite devices don’t have over/under scan or alignment settings but my existing device does, only issue would be audio.

Aren’t HDCP strippers rather expensive though?

There was some exception somehow for OTA HDTV and blueray players, but never seen one where the source wasn't controlled.

Going back to this topic years later…

I finally broke down and bought a cheap Walmart Onn hdmi to rca composite adapter. )it was a whopping $10) so onn 194346525027 (memorable model) doesnt work with roku

I have been told low res outputs don’t require HDCP and this thing lists all sorts of devices dvd, blueray, etc
but on Roku it’s even more nope than my homemade setup adapting the hdmi to vga and then scaling to the crt.

It doesn’t even get a signal (color bars flashing no signal )
let alone give an HDCP error, unfortunate, it’s easy to return but it will mean I need to go through the various Amazon devices until I find one that works.

More unfortunate is the last update removed the ability to set the Roku to 4:3 vrs 16:9

Onns adapter as usual works fine on pc, which is rather pointless for a device like this.
