Strange incompatibiltiy issue with component, anyone know why this happens?

I took the effort of making a video explaining what's happening for me, hopefully this makes everything very simple.

TV is a Toshiba 20AF42.

Basic problem is that I can't enable 480p without the screen dividing itself and looking ridiculous - but 480i just makes it look like composite video.

Obviously, the TV doesn't support 480p. It's displaying it as 480i (480p scans twice as fast, so each scan line is only half the width of the screen, what you are seeing is two scan lines, one after the other, across the screen). And it doesn't display 480i very well.

But why would a TV accept component input if it didn't support 480p?

Doesn't that make zero sense?

like jag said it's an old SD only crt. why would you think it would play anything other than 480i, which can be sent demodulated over component cables.

Well, okay, maybe the question I'm mainly asking is why there is literally no difference in quality between the composite input of this TV and the component input?

[aedipuss]

there is but the tv may not be good enough to show any difference.

The main difference to look for would be dot crawl artifacts with composite. Colored objects on colored backgrounds should be a little sharper.
