It could output analogue 720p and 1080i for sure, but the CPU had a hard time keeping up with HD video decoding. It was only a 733mhz Pentium 3 after all.
Although to go on a tangent, it turned out that you could swap the soldered BGA processor for a socketed 1.4ghz Pentium meant for a desktop PC, using an incredibly cursed interposer setup to redirect the CPU pins to the right BGA pads, and it somehow actually worked.
Wow, you're not kidding saying that it's cursed. I thought it would adapt a socket to the BGA pads, but it looks like the pins of the replacement CPU just sit naked on the interposer.
I think Pentium 3 sockets were through-hole, so to use one they would have had to fit two different footprints on the bottom side of the interposer without any overlap. It might not have been physically possible.
What problems are these widgets supposed to solve?
With such a widget: The video is still at most 720p or 1080i (because scaling, like cake, is a lie), it still originates as an analog signal (that's all the OG Xbox can provide), and the machine is still broadly incapable of playing high-definition video (it's too slow).
