Question Why is my component video outputing distorted video?

So, right off the bat, I'm going to explain why I'm using component video. I'm connecting to an old projector that does not support HDMI (the best it can do is Component). I've heard that some people convert the HDMI to VGA, but my projector outputs all VGA connections as 4:3, which will squish the 16:9 HDMI signal.

Essentialy, I have four HDMI inputs: a TV tuner, an Xbox, a FireTV, and a PC. Those are fed into an HDMI Switcher (https://www.amazon.com/gp/aw/d/B008D6YZXG?psc=1&ref=yo_pop_mb_pd_title) which then runs into an HDMI to Component adapter (https://www.amazon.com/gp/aw/d/B074Q6M7XR?psc=1&ref=yo_pop_mb_pd_title). The projector only accepts Component, however, over the VGA connector, so I have to use this cable to connect.

The video that is displayed, however, ends up with horizontal lines that move around, causing, for example, stationary vertical lines to appear to shake. This happens most noticably on the FireTV, which is set to 720p output, while everything else is set to 1080i. Bending the Component to HD15 cable, however, also causes the quality to change dramatically. I think that the cable I got was somewhat defective (or maybe they're all that way), but is there any reason why the FireTV is more distorted than the others? Is there anything I can do (at a reasonable price point) to fix it? Thanks.

Video format - you also have to know what Frame Rate is being Output by the Source, How it is handled by the Converter (straight through from the description on the link) and what the YUV Input on the Projector accepts.

Source > Converter - ensure you have both set to the same format and avoid 24fps on the Source.

Deinterlacing - is potentially why you are seeing horizontal lines 'buzzing' and is going to vary with the way the various devices are configured, try setting the Source and Converter to Interlaced and reduce any double conversion.

Options - we only ever use/supply the HDFury2 converter, HDfury Fury2 – The Media Factory

Thanks a lot Joe. I think I've solved the problem simply by switching the FireTV's resolution to 1080p 50Hz instead of the original 720p 60Hz. The lines are almost completely gone.

...Is a cheap as chips solution with performance to match.
To feed a component signal into a VGA connector there should be two more connections for horizontal and vertical sync.
See here in the RGBHV section.
VGA connector - Wikipedia
The missing H and V connections are most likely why your signal is so distorted.

Really though, converting HDMI to analog is a faff thats best avoided.
If thats out of the question then joes solution , the HDfury, is really the only commonly available solution that is in any way reliable or usable.

Piecing together solutions from cheap amazon third party sellers always results in what you have now and is a false economy.

'The missing H and V connections are most likely why your signal is so distorted' - quite a few 'Pre HDMI' HD Display devices had the ability to switch the HD15 Input between RGBHV and YUV.
