This is the one I got. If your just trying to get the xbox running on a budget this works fine

I'm using an external HDMI converter. Amazon listing here.

I'm really not understanding what you're talking about when you say YPbPr and SCART and pretty much everything past the first two sentences.

I've never used anything else besides RCA and as of now, this HDMI converter that I linked above.

Like I said I posted the wrong one by mistake. It's this one https://www.amazon.com/dp/B07V73764F/ref=sspa_dk_detail_0?psc=1&pd_rd_i=B07V73764F&pd_rd_w=7Sx9U&pf_rd_p=7d37a48b-2b1a-4373-8c1a-bdcc5da66be9&pd_rd_wg=QtTjQ&pf_rd_r=7ARH5V0KW0N34P64VHDS&pd_rd_r=d58306ad-f714-4832-a7d8-0343d707f664&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzNklUMjBJT0owUEtFJmVuY3J5cHRlZElkPUEwODc1MzI2MUQwVTVCVENOMjdCSSZlbmNyeXB0ZWRBZElkPUEwNzE4MDU1M1NBSlQ0UUg0SEYzUiZ3aWRnZXROYW1lPXNwX2RldGFpbCZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=
